OK PFC gurus, heres a good one!
Car starts fine, fires right up. Runs for like 2 seconds at 2100 rpm upon start up. Then it just dies. I know it's going to die after a couple seconds so I can keep the idle up by pressing on the accelorator. After about 10 seconds of keeping the idle up in this fashion she idles nice around 1400 rpm untill warm. Then drops to about 730 rpm. Idles nice around 730 rpm all day long. Seems like there is a gap in between start up and and cold idle. Any help would be greatly appreciated. Thanks, Tom |
Come on guys ! No ones been here before?

Hey Mike,
Thank you for your response! You mean go back to the PFC base settings? I have not changed them. I really don't get this. It must have something to do with cold idle. Like I said, if I keep the rpm's up by pressing on the gas for like 7-10 seconds it idles nice around 1400 until it warms up. Then she idles at 720-730. Also, if I start the car warm it starts fine and idles fine, no stalling https://www.nopistons.com/forums/pub...IR#>/wacko.png Any other ideas?? Thanks again, Tom |
did you let the ecu learn the idle?
when you go into the 'etc' menu, then to the switch/sensor screen, what switchs are lit up? |

Hi Mike,
I have not adjusted the idle screw. Think it could still be a problem? Thanks again, Tom |
