Ok I searched and could not find anything on this problem I have. When the car is idling cold and you rev it the revs will go up then drop and the car shuts off. Once it is warm you can rev it and it will go back to idle speed. Sometime while driving the revs will drop and the car will cut off. My mods are in my sig. Anybody have any ideas?

 

bad idle control valve maybe

 

Whens the last time you changed the plugs?

 

health of your battery?

 

I will check icv and the plugs, they havent been changed since i got the car about 5k miles ago. Battery is is very good condition. Thanks guys

 

change them plugs!

 

Check/change the plugs as that's a decent amount of miles to do that and an oil change (obviously). Also, did you do anything to the car to disconnect the battery in a while? Maybe need to do your idle learn on your pfc again possibly.



T.c.

 

Ok the plugs are changed and so is the idle control valve. Also adjusted the tps. Now after some adjusting of the tps the car ran fine. Then I shut the car off and started it again and the idle was bouncing and then it shut off. Also when the car shut off there was a buzzing sound coming from the idle control valve (this also happened with the old one). It started to rain so we had to stop. Do you think adjusting the tps some more would solve it? Do you think the power fc has anything to do with it?

 

i dont see why the programming on the PFC would change by itself

 

How do you redo the idle adjustment on the power fc?
