#114 of 168 Fuel Problems by coolhand1 Aug 22, 2008 (7:20 am)
I have a 2001 chevy s10 4.3 4wd auto, it runs good until it's warmed up, then once it's warm it seems to be not getting any fuel. It sputters and backfires and runs very sluggish, but it's not missin. I've changed the catalyc converter, O2 sensor, fuel filter, fuel pump, air filter. I don't know what else it could possibly be. Any suggestions would be highly appreciated. Replies to this message: ridetrue (Aug 14, 2009 10:06 am)

#117 of 168 S-10 power loss/engine shut down when hot by gk10 Sep 08, 2008 (1:25 pm)
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!

Replying to: gk10 (Sep 08, 2008 1:25 pm) GK10,   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.

Replying to: fte003 (Jul 15, 2008 8:51 am) I feel for you and all the rest with the stalling problem. My son's 1995 4cyl, 5spd S10 stalled at various run times (distances) over a 4 week time frame. Seemed like a heating problem (vapor lock or temp sensor causing the computer to shut the engine down). Changed the thermostat and fan clutch. No fix. When driving to troubleshoot had to get gas, noticed an abnormally long time of venting when cracking the fuel tank cap open. Left the gas cap off and low and behold no more stalling. Apparently we have a vacuum being created in the fuel tank as the fuel level drops which the fuel pump can't overcome. The stalling happens quicker the lower the fuel level in the tank. Checked the fuel tank cap for release of vacuum by applying a suction on the cap. It does slowly release the vacuum but not as fast as the vented gas cap in my '93 S10. I suspect I have a bad cap. It isn't clear from the manual I have if there is supposed to be an additional way to vent the vaccum out of the fuel tank other than the fuel tank cap. According to the maunal the charcoal vapor vent canister and closed fuel tank system wasn't implemented until 1996. Maybe our truck is a late '95 which includes the close system. Hope this helps you all out, Good Luck. Replies to this message: bigdaz (May 14, 2009 1:43 pm)
#120 of 168 Stalling/dying by mthompson1 Sep 13, 2008 (6:42 am)
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? Replies to this message: hayman1 (Dec 15, 2008 4:18 pm) hayman1 (Dec 17, 2008 1:37 pm)

#123 of 168 99 chevy S-10 engine cuts out by bethsman Oct 13, 2008 (3:24 pm)
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. Replies to this message: peterhailey (Oct 14, 2008 6:50 pm)
