Chevrolet Cobalt won't rev up or idle properly

SOURCE: 1989 Chevrolet C1500 with 5.7L V-8. Engine dies

fuel pump is working but when accelerating it doesnt pump enough fuel up to the engine then it will fall on its face if it is a electric pump you may have to drop the tank if it is inside and replace it if it is on the engine replace it thats what is exactly wrong with it

Sounds like your fuel Injector's. Go to the dealer and let them listen to they sympton. More than likely they will tell you that it's your injectors that need replacing.

make sure your parking brake is off first then if you take a hammer and hit the side of the drum while you tug on opposite side and do this all around it pulling evenly it will come off. hope this helps.

Follow your air intake boot to your throttle body, your Idle Air Control will be the sensor with two torx bits ussually 20 bit. It is the sensor with the longer flat electrical connector the one beside it with the round pushi in plug is your tps.
