Has anyone found the answer to the S-10 acceleration/engine quit probem? I'm having the same problem with my 2000 S-10 as others have mentioned. One the engine has heated up (primarily in warm weather) pressing the gas pedal causes bouncing on the tachometer and loss of power. If I stop, I have to turn off the vehicle and restart to get it moving again - at a snails pace. The idle has started to increase and will pull the vehicle at about 25 mph if I don't tap the gas. I occasionally smell gas outside the vehicle if I recently filled the tank. the check engine warning light came on a couple of days ago. Last year I paid over $2,000 for transmission work which did not fix the problem. Before spending any more money I would like to have a good idea of what the problem is. Thanks! GK10

Replying to: gk10 (Sep 08, 2008 1:25 pm) So far I have not been able to figure this problem out, yours sounds a little bit worse than mine but the same issue of once it gets warm the idle speeds up then after driving it for a little while it acts like the engine is starving for air. I will have to pull over, shut the engine off and start it back up again and it is fine (the idle returns to normal). I have 2 other sensors that I am going to replace to see if these are the problems. The Air Flow Sensor or the TPS (Throttle Pos Sensor) if these do not correct the problem I have been told the PCM may need replaced. |

I have an 88 S10 2.8 fuel injected 5 speed manual transmission. Truck will start, but will not stay running unless you feather the gas to try to keep it running. Once it backfires through the carb, it throws a code 24, which is a speed sensor. I cannot find this speed sensor. They say it is on the tail end of the transmission. There is no electric going to the back of the transmission. Replaced fuel pump, fuel filter, cleaned throttle body injectors, checked all wiring, grounds...still having problem. Is this possibly a computer problem?

| my cat plugged up a while back and i just put a straight pipe on it, i was wondering if i could trick the 02 sensor because its running a litlle fat and i was wondering if i put a new cat on if it would clog up( if there is some reason it clogged up other than miles and age), truck has 130,000 miles it is a 2.2 liter engine i have a header on it. thank you | |
I have a 99 chevy S-10 with the 2.2 engine, manual trans. and 135K miles. My problems started about 2 weeks ago, when driving at a steady speed if I try to accelerate the engine tries to die. The best way I can describe it is, if you press the brakes to stop and don’t press the clutch that jerking motion the vehicle makes, it happens for a second then everything goes back to normal. Except for 2 times it did something different. One of the times I was in fifth gear and went to accelerate nothing happened (engine did not bog down or speed up). The gas pedal was all the way down to the floor after about 45 seconds the truck sped up. Then the other day I was making a right hand turn and all my lights dimmed and the oil gauge on the dash went to zero, my battery gauge went to about 9 I lost power steering. I thought my truck had stalled but the engine was still running and sounded really bogged down. After a minute of coasting the truck went back to normal and ran good the est of the way home. I have not drove it since. The plugs, wires are good. replaced the fuel filter, got gas from a different station but it did not help. I’m lost on what the problem is. I have been told it could be the fuel pump, short circuit, cam shaft position sensor, timing chain, injectors, or the computer. I'm getting no check engine lights. If you could give me any help it would be greatly appreciated. Thanks again for your help.

ive been dealing with this problem for months now...replaced almost everything...fuel pump, spider injector(which was conversion to multiport), fuel filter, aif filter, spark plugs(twice) spark wires, distributo cap and rotor as well as distributor itself, alternator, battery, ignition coil, map sensor, catalytic convertor, but the truck still wants to buck and cut out when cruising on highway and either going uphill and putting it under a load...or just when i pass a car and come off the gas...does it one day, then not the next, then does it for a week straight, then it goes off....only thing is one day when i shimmied the main harness that runs across the intake plenum it kinda got better for a day or two....did it again and i got no help....im about two steps away from driving it over a cliff i need some help!!!
