I know this issue has been beaten like a dog but I am at my wits end. This site is extremely helpful so first let me say thanks to all who post. so, 2002 ZR2 4.3 was running mint then I got a P0304. Spark plug wire arcing out so I decided to do plugs, wire cap and rotor. 80,000 miles from...

So first off. Long time viewer, first time joining. Ya'll have been very helpful. Second. About 3 months ago I bought a decent Frankenstein. 1987 frame, 1992 body and drivetrain (2WD). Luckily the person I bought it from had the mechanic in mind, so its a not so fresh (2or3years) rebuilt 1992...

Hey everyone! Back with a couple questions about my old s10. I bought it about a year ago for $1000. 5 Speed/Ext Cab/250k miles. Since then I've replaced a horn fuse, wipers, front brakes/rotors/calipers and wheel bearings, fuel filter, tires, oil pressure sending unit, some vacuum lines (but...

Hello, community: I've been chasing a misfire on cylinder 3 for a while now. And then this happens; I'll run it back to a month ago or so, the persistent P0303 (Cyl 3 Misfire) code disappeared on its own, yet a new P0420 code appeared. That's the cat. That's an "easy" fix. I just brought it to...

I have a 01 Blazer 2dr, 2wd,5spd, 4.3l, and the original motor blew up so I put a 4.3 from an Astro Van in it. The van was running perfectly fine before someone rear-ended it, and i was able to snag the motor. The van was automatic but everything looked the same, i plugged everything in, and...

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...

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...

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...

I bought a 2003 Chevy s10 4.3 a few months ago and for the first few months I had no problems with it but one night I was going about 60 and I slammed down on the gas and the check engine light started blinking. Knowing it was a bad misfire I replaced everything I could think of. I replaced the...

I crashed my 1st gen s10 into a pine tree 2 1/2 weeks ago, which left me a broken foot, hip, jaw in 2 places, and a bunch of cuts and a collapsed lung. So I needed to find an extended cab so I could slide the seat back all the way to get in, and it needed to be lowered for ease of access as...

Hello! My truck has been throwing some mixed signals this year. At first she was giving me a P0301, so I changed all the electrical components (sparks along with the wires, distributor rotor and distributor cap). I also installed a new fuel pump and the air intake is in perfect condition (clean...

Replaced distributer cap and rotor as well as plugs and wires, did not change a thing. Tested for spark from cap and wire and plug all spark is good. Did compression test, all cylinders read at 150 within 3 cranks. Compression is good and spark is good so I’m replacing the injector with the...

99 s10 noisy rough engine, losing oil pressure, truck dying I just bought a 99 Chevy s10. We bought it, and it was working great. As soon as we got onto the highway, we noticed the oil pressure drop to 0 and the truck dying. We were able to restart it, and start driving again. A few miles down...
