Currently in the process of trouble shooting a p0304 code. Ruled out a bad coil pack by hooking an ohm meter to it and also swapping cylinder 2 & 4 to see if the the Mis fire would follow. Replaced spark plugs, plug wires, and put a can of sea-foam in the intake. Not hearing any abnormal sounds coming from the engine while running. Just a steady misfire on 4. I’m thinking it is a bad injector. Anyone else experience something similar, and to also see if anyone yet has tackled changing the injectors on the new models. Thank you

My Suburban's sound system has recently gotten blown out. Does anybody know the size for the front and rear door speakers? I'm considering on putting an aftermarket sound system into the SUV.

Hello all, This is my first post on this forum. Last year I bought a 2009 Chevy Silverado 1500 Ext cab LT with a 5.3l V8 that is Flexfuel capable. Well, I never intended to use flex fuel, but last week, I did so on the spur of the moment. We drove about 3/4 of the tank gone. Then as I was pulling up to the gas station to refill before going out of town for work, my truck's idle began dropping and feeling like it is about to stall out at idle. This happens whether park is engaged or not. I filled up, put some seafoam in my tank and drove about 1.5 hours to work. It continued to idle like this all throughout the trip and even later when I went out and sat at idle while on my break. What could be the problem? I can't imagine that an engine that is meant for flex fuel could get that messed up by it. A side note: we had the transmission rebuilt in January, just in case that makes a different. It has only been a few weeks since last oil change. All fluids were checked and filled up at that time and have been checked a couple of times since.

Looking to put proformance muffler on my 2019 trail boss, it comes with the “dule” exhaust, any suggestions which one to go with to give it a little something that I feel like it’s lacking. Had dule magnaflow on 2008 gmc slt, that was great. Any thoughts would help

I would like to change the regular bulbs in my Front turn signals on my RST to LEDs. Does anyone know what bulbs these are (they are marked 855)? Any recommendations on LED's that won't require resistors?

Zane & Josh Merva The Merva Brothers - Co/Founders, GM-Trucks.com GM-Trucks.com is always trying to stay on the bleeding edge of General Motors vehicles and the aftermarket accessories that owners install on them. That’s why we occasionally purchase long term pickups to better understand the ownership experience of these extremely popular vehicles. Our last truck, a 2011 GMC Sierra All Terrain, continues to serve us well all these years later, but became outdated in 2014 when the K2 generation of trucks was produced. We never had a chance to purchase a 2014-2018 Silverado but had a half dozen close friends who let us work on theirs. So when GM announced that the 2019 model year Silverado and Sierra would be brand spankin' new, we knew we had to have one. Thus, a year long effort was set into motion during the Winter of 2017-2018. Internally, GM-Trucks.com declared war on the 2019 Silverado. We could cover it, we would own it, we would be THE place for owners of the T1XX generation to call home. To do that, we had to have one ourselves. We saw the surprise unveiling, followed trim level news, ordering information, factory startup, placed an order the first day we could, then waited (not so) patiently for it to arrive. In September 2018 we took delivery of our new 2019 Chevrolet Silverado LTZ. Here it is a few seconds after the first time we saw it. What’s the plan? We’re going to make our new Silverado work for us and you. Over the next few years we plan on transforming our truck, installing loads of aftermarket parts, and reviewing everything in the process. Our thought process behind this Project Truck is simple. We originally wanted to buy a Silverado Trail Boss but found that Chevy wouldn’t let us get it with the all new 6.2L V8. That engine and the brand new 10-speed transmission was reserved for those who purchased an LTZ or High Country. With the 6.2L being more important, we acquiesced and ordered a more expensive LTZ instead. Thus, our mission to replicate the Trail Boss’s off-road stance and beefed up attitude but with a legendary 6.2L engine and a more luxurious take on things was born. We've decided to call it…. Project Trail Beast More than just a name, Project Trail Beast is a set of core vehicle modification goals that we’d like to accomplish with our 2019 Silverado LTZ. The ultimate goal is to create the truck that Chevy should have made… a Trail Boss with a 6.2L engine. Thankfully, we’re not bound by factory parts anymore, so we can go a little more hardcore than Chevy would have. Our goals include: Suspension Lift: We’ll take our Silverado and raise it a modest 2-4 inches. More aggressive tires are a requirement and aftermarket rims are being considered to complement the higher stance without sacrificing driveability. Beefed Up Performance: 420-horsepower stock isn’t bad…. but isn’t nearly enough. We’ll explore adding a supercharger to our 6.2L and work with leading brands to install performance intake and exhaust systems. We’ll also check in on the custom tuning scene and how the 2019 models can be modified on the inside. Updated Lighting: Even though most of our Silverado has high tech LED lighting, there are still some conventional bulbs. We’ll replacement all with the latest LED tech and add additional illumination around our truck. Expect us to talk about and review industry players such as Sylvania and Baja Lights soon. Utility Accessories: We'll explore bed covers, floor mats, security products, custom keyed locks, ceramic coatings, and a wide range of other accessories that any truck owner may use or need on their vehicle. From Adams Polishes to Husky Liners, we’ll look at what works and what does not. GM Official Accessories: GM is upping their game and offering lots of performance and visual accessories right from the dealership. We opened up a parts account and immediately started buying. How do these products perform? Are they worth the price? We'll let you know Help Us Out! What Do You Want? Do you want a particular product reviewed? Can't decide on a truck safe? Or confused about Ceramic Coatings? Let us know! We’ll do our best to review anything we can on Project Trail Beast. Do you work for a company who has a product you’d like us to look at? We can do that too. What’s next? It's time to get installing. We have a fat pile of accessories we've already started to work on. Each product, each experience, we'll share with you. Stay tuned for more updates on Project Trail Beast.

Lately, my Silverado VortecMax has had a bunch of numerous issues. I recently charged the battery and it suddenly died again trying to turn the truck on. The engine rebuild was also a complete failure. When the Silverado reaches 25 MPH whilst driving it, the truck starts to vibrate. Smoke especially comes out of the engine despite that it's not overheating at all. However, the car on the outside and inside are in pretty good shape except it has a dent on the side.

Chevy passed out a 2019 Silverado information book to journalists during this week's media drive. I'm working on scanning the entire thing and sharing it here. There's a lot of information packed into this flip book. I thought the most interesting was the engine line up and an AFM vs DFM diagram. This is the best comparison blowout diagram I've seen so far. Here's the four pages related to the engines.

Zane Merva Executive Editor / Publisher, GM-Trucks.com April 12th, 2019 A few months ago we started to notice something on our 2019 Silverado that no owner of a brand new vehicle wants to see. Rust. Specifically on our rear bumper, just around the plastic step. It wasn't huge and didn't spread very far from the edge... but we couldn't stop noticing it. There was no excuse for rust on a 8 month old vehicle with less than 10,000 miles. The photo above shows the minimal but noticeable rust patch. It was even happening on both sides and in the same place. The issue seemed odd. Unfortunately, we've just been too busy to bring it by to our local dealership for them to look at. Lucky for us, our procrastination has paid off, because in the time between us first noticing the problem and getting off our lazy asses to drive to our dealer, GM has released a TSB about this very issue. It appears that on most of the early trucks, production of the bumper was completed incorrectly. The steel assemblies should be bent into shape then chrome plated. But that didn't happen in a small part of the early bumpers. The supplier bent the area around the side step after the bumper was chromed. The new folds in the steel damaged the chrome, cracking it and making the truck susceptible to rusting. What's the fix? If your bumper is rusting already, Chevy and GMC will replace it. If it has not yet started to rust, they will apply an automotive grade wax/sealant to prevent rust in the future. If you're unsure if your 2019 has this issue we suggest doing the following: 1. Give your truck a bath for heavens sake! 2. Clean the rear bumper step area with a hose or pressure washer. Front and back! We find lots of dirt collects behind our step in the bumper assembly. 3. Inspect around the foot step area and behind the foot step area. We found rust in both areas! 4. If in doubt, wait for it to rust and kindly ask for a new rear bumper. Our dealership, Banks Chevrolet in Concord, NH has been great getting our rust issue fixed. Our service adviser Justin has kept us in the loop during the repair and gave us a loaner Silverado LT while they have our truck. He even made sure any other outstanding service updates are also applied to our LTZ while it was in the shop. As it turned out, there were six open issues that needed addressed. Here's the official Service Update you can print out and bring to your dealer when you take your Silverado or Sierra in for service.

Zane Merva Executive Editor / Publisher, GM-Trucks.com March 22nd, 2019 The all new Chevy Suburban & Tahoe along with the all new GMC Yukon have been caught testing on public roads once again. We've licensed these images so we can show you the very first look at production lighting for these future 2020 model year vehicles. The last time we saw pre-production models of GM's full-size SUVs was last fall when the 2020 Tahoe and Yukon were caught on film for the first time. This time, the trucks look more complete and almost ready for action. Here's what our spy photographer has to say about the 2020 Suburban, Tahoe and Yukon: And here are the images:

My Suburban was suddenly overheating whilst driving it. Does anybody know if the '07 Chevy Suburban LT have an electric fan? However, I do know that my '07 Silverado (VortecMax edition) has an electric fan.

I drive a 2014 Chevy Silverado with factory 22s and 285/45/r22 tires. I plan on putting a leveling kit on it and getting some bigger tires to beef it up a little bit. Thinking about a 3” leveling kit in the front with 1” blocks in the rear. (Just running a 2” leveling kit in the front would be an option but I’ve heard you can only get 33s under there) A few questions: does anyone have any experience with a setup like this? What’s the biggest size tires I could get? (I’m assuming I could get 34s without rubbing). And also, what are everyone’s recommendations on tread width? I’m wondering if I should stick with a 285/55/r22 or upgrade to something a little wider? I appreciate any help!

Alright everyone... now that we've seen what the all new Sierra will look like, I think it's time for a good ol fashion'd vote down. Which truck do you like best? Which one would you buy? Which design do you like better? There can be only one! Place your vote now. VERSUS and of course, this is all just for good fun.

trying to put together a swap for a 75 custom deluxe and was wanting the 6l80 transmission for the efficiency. would it work with a 4th gen 2005 5.3 out of a silverado?
