I have a 2004 Sierra 4.3l v6 that has started to run pretty rough on idle like it wants to bog out, I noticed my exhaust tips black (don't know if that matters). I checked the codes and got the P0300 code random misfire. I have replaced the spark plugs and the spark plug wires as well as the ignition coil, distributor and the distributor cap. That did not seem to solve the problem and I've ran out of ideas. Anyone might have some insight on what it could be that is causing this P0300 code?

I have a 2004 GMC Sierra 4.3 and lately it's been like losing power when I'm driving down the road it acts as if it stalls and I pump the gas pedal and it turns back on or regains power. I have replaced the fuel filter, fuel pump, speed sensor, mass airflow sensor, spark plugs and also cleaned the throttle body. Do y'all have any idea what could be causing my truck to be acting like that?

I want to start by saying i understand i am working my truck a tad hard. And I AM going to continue. I just want to protect it as much as possible while doing that. I have a 2014 silverado with the 4.3 v6. 102,000 miles and never a problem. Owned since new. When i haul heavy up gravel roads my tranny gets hot like....220-240. I am a carpenter and pull materials and box trailers. I installed a snow plow this year which is snow moving so not a lot of air moving past radiator. I have hit 250 before. I had the transmission flushed at 50,000 and again at 100,000. But i would like to get my temps down. I am thinking an aftermarket fan? An additional tranny cooler? From what i read the tranny cooler is basically built into the radiator. And because the engine runs so hot you wont get too much cooling ability. Also it dosnt start actively cooling until 190? So i guess i need to adjust my thinking to the trucks 190 and up temperature range. But I am not happy with 230 for hours on end. I dont plow commercially just a few small drive ways. Any technical advice, not just opinions(lol) would help.

Hello, I am hoping that you can help me diagnose what is causing a hesitation on my truck when accelerating from a stop. It sometimes also hesitates when shifting at low speeds 10-30mph Truck Specs 2014 silverado 1500 WT 4.3L V6 locking rear end 32,000 miles no codes, using bluedriver scanner red Problem two weeks ago truck took two tries to start never done this before has not happened again last week truck started hesitating on acceleration from stop every time rpms drop from 1500ish to 500ish and then jump back up and truck accelerates I have attached one of the drive logs where you can see the fuel rail pressure drastically change when the engine rpm drops You can see the seven times the truck hesitated at the drops in the graph Started logging other items to see what is happening and found this spike in the temp sensor, attached picture also. intake temp sensor is yellow line and engine rpm is blue line. I highly doubt the temperature actually went from 55F to 135F during my commute. What I have done Checked transmission fluid, truck level and hot. Fluid in the dashed good zone between the holes. No burnt smell. Found the strange temp reading. Truck off Unplugged the mass air flow sensor and drove around large parking lot. Hesitation completely gone truck drive normally for 5 min. Check engine light off. Truck off Plug in mass air flow sensor and drive around parking lot again. Hesitation back Check engine light on with codes for MAF unplugged. Thought MAF was the issue. Bought new MAF and air filter Installed MAF and air filter Problem gone on test drive for 15min, truck fine, no codes. Next day, hesitation is back, no codes Realize I need help. Post on forum. I'm sure I have left out some important information, just let me know and I'll try to answer. I greatly appreciate the help. Thank you.

Hello all. I own an 18 Silverado 1500 LT , double cab, 6’6” box, 6 spd transmission, I have opted to put 26” status alloy empire wheels with tire size of 305/26/30. Stock transmission gave out. Stock Transmission went out. They said torque converter and pump went out then everything else went with it. Was able to replace the entire unit with a remanufactured from GM. 1 month later, back to the shop (dealer). They covered the repairs because it was under warranty but if it goes out again they won’t because they believe it is the rims causing the trouble. However they will cover if it goes out with stock wheels. Which I will be putting back on. Has anyone else experienced issues with this type of truck and 26” wheels? I did research the “Unsprung weight” makes some sense, however only the transmission gave out, not my drive shaft, drive shaft knuckles, diff, just the goofy transmission which I know the 8 speed has had their share of ongoing things. How is it that a truck that is capable of towing 9k lbs has issues with no load on 26” rims. Pulling a payload in the bed of the truck and pulling a trailer should still have the same effect. If I can’t tow anything with the truck, then what is the point of a truck. I have went back to stock rims to see what would happen. Anyone with info ,thought , something sketched on a cocktail napkin would be greatly appreciated. I do thank you all for your time on this. I have attached the service ticket to this post.

I have a 2001 silverado extended cab v6 that is a base model. It came with no power locks or windows. I am trying to convert them. I already have panels,switches and the harness out of a 2002 z71. My problem is I found out my fuse box won't support this. I can provide pictures if necessary. I'm looking for advice on if I can just get another fuse box out of a truck that has the options and do I need to get a new underdash harness as well? Also if anyone has done this swap before any other insight would be greatly appreciated Its a project truck and has sentimental value so I'm not just going to " go sell it and buy a truck with all the options" -
Hi. I own a 2015 Chevy 1500 Silverado 4.3L V6 CrewCab 5.8' Box. Can I swap the rear differential from a V8 1500 Silverado onto my 1500 Silverado? According to chevy I can tow max of 5,600lbs, I blew out my rear differential from towing 5,300 pound trailer, bearings are shot, shattered.

Hey guys, Just wanted to post a positive experience on here! I bought a Silverado 1500 Crew Ecotec3 4.3 V6 about a year and wanted to write how impressed I am with it. I looked down yesterday and I was cruising at 94 with no problems at all. I was just keeping up with traffic when I looked down at the speedometer. I had to slow down because I didn't realize how fast I was going. The thing still had plenty of power cruising at 94! I'm the type of person that won't be hauling a trailer or anything super heavy behind it, so I don't have any information on how it handles those things. I came from an 04 Avalanche with a V8 and honestly, I can't notice a difference in power at all. I do think they're rated about the same horsepower though. All around, I couldn't be happier with the purchase. I have never gotten in my Silverado and regretted my decision to get it over a Camaro. Just wanted to post a happy post today!

2005 silverado reg cab short bed 2wd 4.3 v6 5 speed manual 63,000 miles Driving on the highway I downshifted while braking for a ramp and all the sudden my engine idle got stuck between 3800 and 4300 rpms. Limped home with the truck under what seemed like constant 20 percent throttle while in gear by itself. take it out of gear and it revs up to 4000 again, incredibly hard to put in gear and kinda dangerous to drive. No cel and nothing stored in my code reader, wondering where to start on fixing this? Pulled on throttle cable and seems free, spring is good and throttle moves. Can I replace a solenoid? IAC? Brake booster blow a vacuum line? Thoughts on this would be appreciated.

I am hoping to start up a good conversation on upgrades/information/etc on the 4.3L V6 Ecotec3 engine. There isn't much info on here about it. Well...I can't be the only Silverado 1500 owner with that engine. Just looking to see what people have done. Any issues? Just a good informational forum/topic.
