Does the car stall and not start unless it sets for awhile or does it start right back up?

Is the check engine light on?

How many miles on the car?
Customer: replied 7 years ago.
The car always starts right after it turns of. The check engine light is not on. The car has 68k miles on it
Expert:  Michael Moore replied 7 years ago.
If the car starts back up as soon as it stalls, then more then likely the fuel pump may not be the issue. A loose connection at the battery could cause this issue or a dirty throttle body could also be the cause. Check the battery cables, they should not be able to be moved when pulling on them.

Here is some information on your car for a stalling issue.

#PI01525A: 2.2L L61 Engine - Stall Hesitation Stumble with No DTCs - kw idle intermittent misfire miss rough surge - (May 24, 2004)

Subject:2.2L L61 Engine - Stall Hesitation Stumble With No DTCs

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.


Hesitation, stumble or stall with no DTCs. This usually happens when the customer is slowing to a stop, with a clutch apply for a manual transmission, or slowing down in an automatic transmission equipped vehicle.


If normal diagnostic procedures are unable to find a root cause for the condition, the Idle Air Control Valve could potentially cause this problem. Replace the IAC, part number 88984174. Also a revised calibration was released in May 2004 for this problem. Reflash the PCM with the latest calibration available.
