Im new to this forum, and have recently been having problems with my 2000 S10, a couple months ago it would randomly short and everything electrical in the car would turn off and on, and as time went on it would get worse and not come back on. So i took it to a Goodyear and they said it was a loose bolt on the fuse box or w/e, which appeared to fix it. Until now...it has come back with a vengeance, it'll die, and after jumping appear to not have full power, go 10 feet and die again. So i dont know what to do to permanently fix this aggravating problem.

| ok I hope someone can help. I have a 96 s10 truck manual 4cyl. It has been a great truck until now. Twice now it has stoped on me when I am ideling. It stops and won't do anything. we let it rest for 15 minuts and it will start back up again. After the first time we thought it was the fuel pump and so we first changed the fuel filter, it was clogged bad. Now after it happned the second time we now think it might be my computer system going out. I had a mechanic look at it and we had it running for 2 hours and it only stoped once and started up right away, not like it has been while I was driving it. I don;t need it anymore I just want to be able to sell it running. Any help on where to start would be great. I have many people telling me different ideals but no one knows for sure. | |

Hitting any bumps? At Idle? When you say "not come back on" do you mean it wouldn't start or it didn't flicker off and back on like your lights in the house during a thunder storm? In all instances, I would check and make sure your battery cables are connected well to the frame for the ground points and to your starter/alternator on the hot side. There's something definitely loose on the ground or hot side OR rubbing between hot and ground somewhere creating a shot. Be sure to check and make sure all your fuses are in perfect order as well. Was any electrical work done to it lately? New starter? Alternator? Stereo or alarm install? Subwoofer / Amp? After market DVD player? Sounds like it may be a dead short. Look for anyplace a hot wire may come into contact with ground. That's the reason for the questions about the electrical mods. I've seen where people install stereos themselves and tap into a hotwire under the dash and not insulate it where it rubs on the chassis or dash and shorts out. Was the bolt on the fusebox a ground bolt? Check for more loose bolts in that area if the fusebox bolt was a grounding point. Loose connections will temporarily disconnect and surge power like you describe also. That's the best advise I can give you with the information you posted. Good luck, vi-kan |

My 96 S-10 (4 cylinder) sputters when accelerating. This gets worse as the engine warms up. Sounds like it's poping/backfiring in the throttle body sometimes. There is no check engine light at this time.

During warm weather (mostly summer months) my 2001 S10 has a problem with the idle speed increasing, once I notice the increase in RPMs I can shut the vehicle off, restart it and it goes back to a normal idle. The idle will remain normal until I drive it again for a few miles. I have taken it to a few places but each time they look at it the idle speed does not increase. This problem surfaced the other night and when I tried to pull away from a stop the vehicle about died. The funny thing is I can drive this vehicle for hours in colder weather and it will never occur. As stated this is a 2001 S10, 2.2 engine, auto and about 125,000 miles on it. All preventive maintenance is completed on time. I have a feeling it could be the 2 different sensors or the Idle Air Controller. Any suggestions would be extremely helpful.

Replying to: lilgto (Jun 27, 2008 11:30 am) If you suspect the IAC, have you tested it yet? From what I've read, the IAC valve is something that receives data from other sensors as well. Coolant temp, AC, accessories etc. It is supposed to compensate for the load you are putting on the engine. i.e. if you turn the AC on while idling, the engine would normally slow down due to the increased load, thus making the IAC compensate for that and speed up the engine to keep is from stalling. If you disconnect the IAC while the engine is running and put a load on the engine, the engine should stall which indicates the IAC is working. If this is the case, the IAC probably isn't the problem. Sounds like it may be an air blockage issue. Maybe a vacuum line that is restricted or pinched that is plugged into the intake? You know how an engine will speed up if the choke is on? Same principle in my opinion. Good luck.

Replying to: vikan (Jun 28, 2008 6:02 am) Thanks for responding, yes I have tested it and even changed it out but it has started happening again during the warm weather. I have been looking for vacum leaks for some time but so far nothing. I am thinking the problem might be in the PCM since the fast idle issue disappears whenever I shut the vehicle off and restart it. I will keep trying to figure this out since the mecnanics seemed to be puzzled. Once again, thank you for your prompt response.

Replying to: lilgto (Jul 05, 2008 6:00 am) After a quick search on google and reading from this Q & A, it sounds like there may be something shorting that leads back to the PCM. You might want to do a little reading here and maybe even post a question to these guys. I'd hate to see you spending money on guessing what might be wrong, only to have to spend more on something else. I know it gets frustrating so hang in there. Personally, I think at this point, I would attempt to find a schematic that shows you what connects to anything that has to do with idle speed. http://www.2carpros.com vikan
