Replying to: fte003 (Jul 15, 2008 9:51 am) Have you checked to make sure you have no air restriction? I'm assuming this vehicle has a throttle body. If it starts with no problem, remove the air cleaner. watch the butterfly on it to see if it closes on it's own once warmed up. Wrap the engine to see if it's operating properly. Next, I'd run it without the air cleaner (on the highway away from dusty environment) to see how it acts. If it does die, have someone crank the engine and see if your butterfly is in the closed position which would be choking it.   Another thing to check is your vacuum lines going to the intake. If the idle seems rought spray a soapy water solution around the vacuum line fittings. If the idle smoothens when water is sprayed, you have a vacuum leak.   The last possibility I can think of without spending a lot money is vapor lock. Make sure your vent lines for the fuel tank are not plugged. I believe the engine compartment holds the gas fume recycling canister (not the exact name) which has vent lines that run from the fuel tank to the canister (charcoal filled for emissions) and back to the tank again. The easy test would be to drive without your gas cap on.   Good luck.

Replying to: sjowett (May 29, 2006 4:58 am) after it dies spray some starter fluid into intake and see if it starts, if it does you have a fuel prob, if it doesn't you have an ignition prob. If it has an electronic ignition module i would suspect that, you may do a spark test after a no start
#113 of 120 GMC 1996 Jimmy by lran Jul 28, 2008 (7:54 am)
Hi all I am starting to have a issue. My truck ( 1996 jimmy v6 vortec) has ran flawless, but all of a sudden I will be driving down the highway and it just quits. I put it into neutral and it starts up and can drive again. Sometimes for an hour or 2, and sometimes it will do it again right away. This is happening when the vehicle is warm and at highway speed. When I am in town this rarely happens, it will only happen if I just came from the highway and am just getting into town it might just die. I thought it might be a bad batch of gas, but it has happened for a month now. I thought it might be a new stereo that I got put in, but it still happens when I leave the faceplate off the stereo. I am at a loss of what to start to check what is causing this as parts for this truck are extremally high. It has had regular oil changes and has recently had a tune up.   thank you for any suggestions.
#114 of 120 Fuel Problems by coolhand1 Aug 22, 2008 (8:20 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.

if i pour gas in to the throttle body it will start, and run for awhile then die in a few minutes, and when it is running it will idle and if im easy on the gas i can drive it for a short time but if i put the pedal to the floor it sputters, i have put new fuel pump with wires, mass air flow sensor, hollowed out the catalic converter, new ox sensors on exaust, i dont know what else to do, any help would be greatly apperacited

#117 of 120 S-10 power loss/engine shut down when hot by gk10 Sep 08, 2008 (2:25 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 2:25 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.
