If the check engine light is on it could be one of several sensors going bad. If it is not on most likely you have a vacuum leak.

My 2001 Buick Regal will only start if press the gas pedal, when I release the gas pedal to step on the brake the engine shuts off. Any Ideas?


Could be a dirty throttle body or a faulty idle air control valve.
The computer controls idle speed by regulating the amount of air entering the intake thru the throttle body.

My grand cherokee starting very well and turn off by it self


if you can keep it running by pressing on the gas pedal then clean the idle air control valve, IAC.
If, however, it runs for 2 seconds then shuts off and no amount of pressing the gas pedal helps then check your crank position sensor.

Trouble starting, idleing,and cruising without shutting off.


three possible answers to look at ; fuel filter located at the back drivers side by the tank; throttle positiion sensor or crank position sensor[ worst case scenario fuel. pump is starting to fail. gas or fuel filter first; bring the car to advance or autozone for a free scan for trouble codes

'03 Jeep Liberty starts weakly and needs gas pedal to idle


Turning over is what the starter does to the engine ...you can turn an engine over with no spark plugs in it...but you can't start it. Turning over is cranking .....the starter turns (cranks) the engine over (comes from when you had to put a crank in the front of the engine and crank it.)
Does it crank normally but has trouble starting???????

My 98 dodge avenger shuts off instantly after I crank it up. Or if it is running and I stopped @ a red light, my car will shut off. or it will start shaking before it shuts off.


if you press(and hold) the gas pedal down a little while stopped, does the car still die? if it doesn't die, your problem is the Idle Air Control motor. it located on the throttlebody.
