4.3

  1. S10 / Sonoma
    Hey everyone I need help and have searched the forums but cant find any direct answers for my situation. Ok so first off I'm building a off road tracked vehicle and I've bought a 2002 sonoma with the 4.3 for my engine. So it will crank over start for 2 seconds and shut off (passkey yes I know)...

    Hi there! I’ve been looking through the forums all day and haven’t found the answer I am looking for. I have a 1997 s10 4.3 v6 with 4x4. I’m trying to figure out how to fix my speedometer. I went from a 235/75r15 to a 235/50r18. How do I go about getting my speedo back to normal? I’ve heard...

    I have a 2003 s10 4wd with a 4.3! I’m getting a p0305 code which is cylinder 5 misfire! I’ve changed all plugs, wires, distributor, cap, rotor and new fuel filter! Still getting same code very rough idle and really bad fuel mileage! I am now lost at what else it could be and I don’t want to keep...

    Welcome, New here. I just picked up my first s10 (normally a gmt400 guy) it’s a 97 extended cab short bed with 122k kinda clean pa truck. I’m deciding on doing an off-road build but in the process of that I decided to part out one of my gmc Denali’s. It’s a 2000 with a 5.7. My question is that...

    Okay here’s the deal. I’ve got a 1994 ZR2 CPI. Over the course of the past two weeks I’ve installed new distributor, fuel pump, both knock sensors, injector assembly, fuel filter, knuckle kit, egr block off plate, motor mounts, temp sensor, spark plugs, wires, upper and lower intake gaskets...

    today after school when i went to start my truck the gas pedal like popped and it’s never done that before. also when i was trying to start it, it struggled to start (more than usual). anyone had this problem and know what caused it? should i be worried?
  7. S10 / Sonoma
    What do I need to know? I’m looking for info on the things that aren’t obvious. Everything on both trucks is factory. I’m considering using the’98 4cyl rear. ‘96 4.3 is a W code.
  8. Exhaust
    Which would sound better for a deep rumble? MagnaFlow 11226 or Flowmaster 50 942551 4.3l V6

    so if i let my truck sit over night, the next morning it will start no problem, but if i shut it off it will take a bit to start again. everyday after school i have to crank for about 10 seconds then tap on the gas to get it to start. what could be the possible problems?

    I've got a 1992 4.3 Vin Z that threw a rod on me. I'm looking at getting a Vin B out of a 91 Astro to put into the truck. I know there's not many parts available in the way of performance for our beloved V6, but out of curiosity how hard does everyone thing it would be to set it up with a Holley...
  11. Wheels, Tires & Brakes
    Hello everyone. I'm having some trouble choosing what tires I'd like to throw on my S10. I currently have a super 60 front end and a 14 bolt rear sitting in my garage that I am almost done with. I currently have some 37 nitto trail grapplers. I know I'm going to be doing some fender trimming...

    I've been searching this forum for a while and no one has a conclusive answer; can you change the oil pan gasket in a 2nd gen 2WD 4.3L + Manual trans by just lifting the motor a little with a hoist? I have an engine hoist but I'm trying to do this job in 3 days and it isn't worth it to me to...

    Truck is an 01 s10 zr2. 4.3. 4L60E tranny. Recently, I had a vacuum hose leak. Near the charcoal canister due to an open hose. Fixed it. All the codes I was getting (P0422, P0300, P0410, P0452) was cleared and didn't pop back up. Drove it a good little distance the next day. About a 30...

    I just got a 97’ Sonoma 4.3 auto 4x4 flatbed. It was originally owned by Disney in Orlando. My friend bought it from them and has barely used it over the years. It has just under 9,000 miles on it. Yes, 9,000. I just got the truck today and when I turn the key in the on position, I can’t hear...

    Hello. I've had my 1998 4.3 5-speed for three years. It's been kind of a love/hate relationship. I love the stick and the towing power, but I've had a few issues, mostly with the fuel pump. It stranded my several times, mostly due to a poor fuel pump rear frame ground and a poor install of a new...

    Will a vortec take same intake setup as a 1993 s10 with a 4.3l?
  17. S10 / S15
    Alrighr, so i know the 4.3 isnt worth building or putting power behind, but how can i put a new tune on the ecu. I got an exhaust done because i think the motor sounds great, qnd somewhat expected it's runs stupid rich. Like i spit fuel out the exhaust rich. I know i could do the whole eprom...

    So I'm gonna swap my CPI to TBI and had a crazy thought, just wondered if it would even be possible to use the same computer in it. I have a 4.3 TBI throttle from a 91' S10 so I'd have to hook the injectors up in parallel. I just want an opinion, whether or not you think it would work. Either...

  20. S10 / Sonoma
    Ok so I have an 01 s10 4door with a 4.3. I've been having an issue with a cylinder 6 misfire. It only presents itself with anything more than a gradual acceleration to cruising speed (55-60) or when pulling a trailer. I've changed spark plugs, wires, distributor cap and rotor, fuel pressure...
