Question about 1994 Chevrolet K1500

2 Answers

94 chevy k1500 5.7L engine won't run properly.

My 94 chevy 5.7L engine will start but will not idle, it dies. If you try to press the accelerator to see if it will run at higher rpm and hold it, the engine will die. You need to constantly rev the engine up and down just to keep it running. I have replaced the fuel filter, air filter, spark plugs, distributor cap, rotor, and spark plug wires. After replacing parts listed the engine still runs the same. Can anyone help me?

In park the engine dies; only will run if given gas


It sounds like there is a problem with the Idle Air Control (IAC) valve. Its job is to open and let air into the manifold when the throttle is closed at idle. If it does not open, the engine dies at idle. The IAC is mounted on the throttle body. Possibly the valve is clogged or stuck, in which case it could be ok again if it is removed and cleaned. Or it is broken, and needs to be replaced. Or, there is a problem with its electrical connection, that needs to be traced. Good luck, let me know if you have any questions.

1998 Dodge Durango 318 V8. Engine won't idle. Car has been sitting. Battery was discharged - had to jump start. If you keep your foot on accelerator, engine runs smooth. Once you take it off, it dies....


Probably lost idle memory,all computer controlled keep it running for a period it should regain the idle memory if not make sure no rodent chew damage to wires to the throttle position sensor, if check engine light is on scan for faults.

1994 chevy lumina van. It will start and idle but stalls when gas


Try replacing the throttle position sensor. I had the same problem in my truck. It would start and run for a bit but as soon as you let off of the pedal, it would die. Try it and see if it works.

Hesitation , skipping,engine cuts out when accelerating


Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?
