Hi all, 15 Yukon SLT (94000 miles) here So I had a misfire code P300 and engine light blinking late December 18. Done a tune up (replaced all sparks and wires) and everything was fine until a few days ago. Didn't feel any lose of power, vibrations and etc. Got another misfire code, this time P0305 (cylinder #5) a few weeks back. Mechanic looked into it and couldn't reproduce. Had an engine carbon clean up. Again no lose of power, vibration poor fuel economy and so on. Couple of days ago got another misfire P0305. Called the mechanics and he suggested a compression test. Not sure if needed as no other signs are apparent. He also start speaking (worst case) about taking the cylinder out to be inspected and replacing AFM lifters. I've looked into mode 6 on my OBD scanner as saw that cylinders 1,3,5,7 all have misfires, though below the threshold so no codes or lights. Cylinder #5 had count of 78 misfires and the rest (1,3,7) around the 1-5 (thats after a 2hr drive) What I found weird is that the AFM cylinders (2,4,6,8) had no misfires. Aren't those the ones with the lifters? I've replaced the coil of cylinder 1 with 5 and got the same results (higher counts of misfires on 5) so don't think that is the problem. Anyone encounter the same issue? How was it solve? Any suggestions for self diagnostics before its heading back to the a shop? Thanks

I’m planning on upgrading my gear ratio from 3.42 to 4.10 on my 2019 custom trail boss. I want to put a 4-6 lift on my truck from BDS with fox shock coilovers With 35 inch tires maybe 37’s but before that I want to regear my truck so that I don’t lose any power. Do y’all think 4.10 gears are good enough for should I go for like 4.55’s? If anyone has re geared there 2019’s and up please let me know the prices and gear shifting experiences. -
I’m having this issue with my truck. So both fans turn on automatically when I start the truck, also I don’t have no A/C. I replaced my thermostat and temp sensor. That didn’t seem to fix it. I should also include that I did a DOD Delete with a stock non dod cam, it’s tuned and engine works fine. It’s driveable but it’s annoying have no A/C and both fans when I start the truck. Please help! -

I recently bought a used 2016 Sierra Denali 5.3L 4x4 in March with 48k miles. Truck has been great until yesterday (now 52k miles) when I ease into the gas it shudders and shakes like crazy until i punch it. The tach is bouncing up and down and it doesn't matter if it's in v8 or v4. It almost feels like it's a misfire but it's weird that it only does it when I'm easing into the throttle or going uphill. The truck has the 8 speed transmission. Has anyone else ran into something like this and would the manufacturer warranty cover the fix for this? -
"ENGINE POWER REDUCED, SERVICE TRACTION CONTROL, SERVICE STABILITRAK" Has anyone ever came across this before? Let me start from the beginning. On 11/2932013, halfway on my drive from work to home, I noticed that my truck would "sputter" and the rpm would fluctuate when giving it some gas while going up a hill/incline (interstate). Once I was done with the hill/incline, everything would smooth out. Closer to home, once again, I would only notice the "sputter-like" reaction and rpm fluctuating slightly when giving it gas to climb a hill/incline. Made it home fine with no problems or warnings/lights. Upon embarking to work the next morning (11/30/2013), at approximately 5-6 miles from home, I went to give the truck some gas to get above 60 and all of a sudden all these warnings and dings starting going off. My engine warning light illuminated and my traction control light came on and I noticed some warnings scrolling through at the bottom saying: "ENGINE POWER REDUCED, SERVICE TRACTION CONTROL, SERVICE STABILITRAK". it blew my mind! Meanwhile, I noticed my truck slowing down no matter how much gas I gave it. I was coming to a road intersection just ahead and preceded to turn around and pull over to investigate. I couldn't understand what was going on so since I was close to home, I just "limped" it back home and not getting over 40-45 mph. Got home and shut engine off and called my job. I went back out later before my ride got there to pick me up, and started my truck. It started fine and I didn't notice any "sputtering" like before, however the engine light is still illuminated. I can't do anything until this Wednesday anyway. Is there someone that has come across this before? The day it happened I Google'd to my heart's content and found that I am not alone, however I did notice that there can be a number of things that could cause this. Would any of this be covered under a warranty? How would I know if I still have warranty on my truck? I need some expert advice on this. Here is my truck info to the best of my knowledge: 2010 Chevrolet Silverado 1500 LT Taupe Gray 5.3 L V8 Crew Cab Any help will be greatly appreciated! Thanks, R. Ashley -
Which engine is better? I assume the 6.2 has more power and the 5.3 has better mpg, but how much of a difference is it?

I have read hundreds of AFM collapsed lifter threads but have not been able to find someone with my same issue where it has been solved. Looking for your expertise in the cause, not looking for advise to turn AFM off as that is the plan but I want to properly fix the issue first. I have a 14 Silverado with a 5.3 with 50k miles and the issue I’m having is there is a pecking/knocking/rattle only when the truck is under light load while it is in V4 mode. Has anyone else experienced this where the noise occurs only while in V4 and while slightly accelerating? The are no check engine lights, no noises at idle, no noise while running on 8 cylinders, no smoke, no oil usage, and it doesn’t appear to have lost any power. The two possible problems I see are either: 1. One of the AFM lifters have failed in a way where it is not allowing the cylinder to deactivate which means the intake or exhaust valve will function like normal instead of closing during V4 mode. If this is the case is there any way to confirm this without a diagnostic scanner to put the truck in V4 at idle or to deactivate each cylinder? Is there any risk of further failure by not fixing this if I turn off AFM as it seems the “tabs” are just not disengaging within the lifter? 2. There is an issue somewhere within the VLOM portion with an actuator, oil port, something electronic that is preventing enough oil pressure to deactivate the lifter. If AFM is deactivated is there any risk with whatever is not working properly within this system? Basically, I am fine with turning AFM off as where I drive there is likely minimal impact but I don’t want to turn it off just to cover up a problem that will resurface in the near future as I don’t intend on getting rid of the truck any time soon.

I recently became acknowledged about the myth of the 3,000 mile oil change on newer vehicles with advanced oil. I own a 2006 silverado 2500 v8 6L WT and I change my oil every 5k miles with Mobil synthetic 5w-30. I cannot seem to find the exact information within my car manual or my Haynes/Chilton manual for the recommended interval between oil changes. Is there anywhere I can look up how often I can change my oil with the specific engine of within my truck? I have heard some oils can go 10k+ miles on some vehicles. I'd love to do less oil changes, but don't want to endanger my engine since oil changes are so quick though I'd love to save money too! Where can I find this exact information or do you have any other suggestions? Thanks in advance! -
Our experience with the all new Camaro has been outstandingly positive. Just last fall, GM-Trucks.com drove a 2016 Camaro SS over 1,600 miles from Minneapolis to Salt Lake City in an epic road trip. The SS turned out to be a strikingly composed vehicle. In our time with the last generation Camaro ZL1, we were equally impressed but the vehicle's extra weight made it harder to control on the track. This generation is over 200-lbs lighter. The all new ZL1 will dial this lighter generation pony car up to the proverbial "11". Specialized bodywork on the ZL1 improve aerodynamics and cooling. A larger front splitter, unique rockers, larger rear spoiler and wide front fenders are designed to keep the Camaro ZL1 stable at high speeds. A special "flow-tie" Chevrolet bowtie insignia is open to allow more airflow to the engine compartment. Inside the ZL1 has standard Recaro front seats, a suede flat-bottom steering wheel, and suede shift knob. Chevrolet's performance data recorder (PDR) is also available. The ZL1 also comes with unique 20-inch forged aluminum wheels with exclusive Goodyear Eagle F1 Supercar tires [285/30ZR20 Front / 305/30ZR20 Rear]. Those huge tires will get help stopping with massive 15.35 inch rotors squeezed by six-piston Brembo brakes up front. 11-heat exchangers throughout the Camaro ZL1 make this four-person car track ready straight from the dealership. Pricing and availability have yet to be announced. -

Chevy says the engine started with the "...LS steel Bowtie standard-deck block, added a forged-steel crankshaft, forged rods, and forged pistons, then topped off the short-block assembly with high-flow, rectangular-port LSX-LS3 six-bolt aluminum heads for supercharged and turbocharged combinations." The $9,875 crate engine arrives without an intake manifold and no accessories. You built it up. For more information check out Chevy's infomercial on the engine. How would this short-block with a blower do in your dream build? -
The editors at Equipment World said of the Silverado "“Of all the trucks, the Silverado has the best ride and most planted feel, especially towing the trailers we have on the hitch,” I wrote in my test notes. “Silverado is remarkably stable when towing despite us not using a WD hitch; no trailer movement. Quietest interior of the bunch.” Not much direct mention of the engine there. What's your take on this story at Equipment World? Should they have included a Ford Ecoboost? At a glance it looks like the Ford V8 did very well, so perhaps the comparison is valid after all. Note- Image of Silverado 1500 6.2 at top of story was not the exact truck tested. -
