Cars will use more gas idling than starting the car.
Since it is starting from 0, the engine idle is low.
the ecu is reset when you disconnect the battery. after driving for awhile or letting the car idle in drive, your problem should be solved. the ecu is reset when you disconnect the battery. after driving for awhile or letting the car idle in drive, your problem should be solved.
It could well be the Idle Control Valve Or in other terms the Idle Stabilation Valve is faulty
you have a bad alternater or belt
throttle body is not letting enough air in. Idle speed servo, stuck or failed.
I just read this in another forum, so I can't take the credit if it works, But sounds like it might help you. "it should be as easy as dissconecting your battery ground for about 45 minutes then hooking it back up and starting your car without touching the gas pedal, then letting it idle for 3 minutes without touching it." ? give it a whirl.
If, by chance, you let your car's battery die entirely, I have heard of occasions where your car's computer becomes disorientated, or reset if you will, and your idle can get messed up. what i would do is avoid letting the idle drift too far below 750 RPMs and your computer will eventually re-learn what your proper idle is over time.
Did computer lose power? Car may need to re-learn idle. Refer to repair manual for idle-relearn process, or you may get away with just letting it run with foot on gas for a while until it idles properly, however you should refer to proper idle re-learn process. Ensure battery and alternator are good.
no, you should let it idle and warm up a little bit.
When a car, such as a Hyundai accent, has and broken idle control valve the engine may or may not start. Idling is controlled by this part and the car a malfunctioning unit can cause the car to act erratically, such as starting at random times and stalling.
What kind of car is it if its a newer model then the idle position sensor if it's a older car with a carburetor the u need to Clean it and set the idle
More than likely it's your Idle Control Valve.
