SOURCE: Chevy S10 Pick 1995 - Sputters and almost stalls when accelerating.

You could have a dirty EGR valve, you can re move it from the manifold and clean it with Throttle body cleaner. Might as well buy two cans, since your cleaning the EGR, might as well clean out the throttle body too.
Spray the throttle body cleaner in to the throttle body with the engine running and try to keep it at 1000 rpm and then to 1500 rpm as you clean out the throttle body and let it idle down for 2 min then turn the engine off. Then turn the engine to the run position for 10 seconds and start and let idle, ro for a test drive and hope that solved the problem, if not there a few more things we can do which will consist for tune up.
Note: Clean the EGR first so you don't burn your self since the engine would still be cool before you clean the Throttle body.
Good luck and keep me posted.

SOURCE: Chevy Blazer won't start; fuel pump needs replacing

Before spending several hundres on a fuel pump, I recommend doing a fuel pressure test. You can get a test gauge pretty cheap at a parts store. If the pump is junk, you raise the truck, lower the fuel tank, unplug the electronics from the pump at the top of the tank, then with a hammer and flat head scrwedrive, gently tap the lock ring in a counter clockwise direction until it pops off. Pull the pump assembly out and install the new one. Reverse directions to install.

SOURCE: my 2006 chevy cobalt 2.2 liter sputters

Fault with the IAC valve.there maybe a trouble code associated with it also./ Go to your nearby autozone or auto parts retailer and ask them to put a scanner to the car....make note of the codes if any are found. the IAC valve i usually locate don the throttle body and can be removed for inspection and sometimes cleaning using a good throttle body cleaner spray and a pipe cleaner brush.

I have a 1990 chevy s10 pickup, it stalls in reverse and sputters like crazy when driving. I t idle real rough and I have to drive two footed so it won't stall at lights. It also has problems going up...


you could have a fuel pressure or volume problem that will have to be checked out.could be a plugged fuel filter.it could even be a tune-up problem(bad plugs,wires,etc)its possible that the catalytic converter may be plugged and this will have to be testes with a back pressure test.these are places to start.

1992 Chevy S10 2.5L-4 cylinder. just started today outta no were. it idles really rough and pops then when i step on the gas it sputters and pops also smokes a little. help please..


My 1990 S10 pick-up had a similar problem too. It would start up fine (while the engine was cold) then once the engine warmed up it would idle very rough, sputter, and even stall out. My grandpa and I found what was wrong finally. The fuel distributor had been cracked, so when the engine warmed up it would miss (giving either too much or not enough fuel). So I recommend that you check that. Hope this helps.
