Reset the PCM and re-learn the fuel trims properly as specified in your owner's manual.

how old's the battery?

 

[Andre G]

fresh new optima red top...alternators been tested at autozone and says its fine but is it possible to test fine and still be bad?

 

[Kilgore Trout]

When the new battery was installed did you go through the procedure I already f'n mentioned?

lot of milage for an 02. I just reached 50k on my daily driver.

Not quite sure what your problem is....did this start happening AFTER you installed the battery? Maybe you have a loose ground cable connection with the battery and throwing the A/C on wiggles it loose?

 

[Andre G]

no I will try that... I bought the car used in 04 with 45k there all highway miles and i drive to and from college so ya thats why so many miles...

My car did the same thing when I blocked IAC to make RPM drop faster. So i would start with IAC. clean it, and see

yeah man, that mod sucks! check the IAC as mentioned, they seem to be the culprit of idle issues stalling
