 Posted: Wed Jun 25, 2008 5:41 pm Post subject: I second Death |
 |
|
| My EF has a strange thing goin on where if I let it sit and idle in the driveway it runs perfectly except for every 2-3mins or so it almost dies for 1 second then returns to normal. It's like the thing chokes on something almost cutting it out, it sort of makes a venting air type sound at the same time. I know it's a bit vague but it's the best I can do. The prob doesn't really concern me as the car runs very sweet otherwise, but there is obviusly a minor prob with it, any ideas?? |

-replace fuel filter
-check fuel pump (put your ear near it and see if it stops making a noise while its almost dieing)
-Clean the ISC |

Clean the contacts of the ISC plug?
Although I would say it's just the ECU re-learning the idle via the ISC. That venting sound is the ISC. I have been in a few ef/el falcons that do this, it's really nothing to worry about.
I think to fix it you just have to re-adjust the base idle speed with the ISC unplugged. You will need a set of feeler gauges to do it . |

My impression is the ECU has a pre-determined idle speed that it tries to maintain, and there is no provision for adjusting this. |

you can adjust it, just need to short the top and bottom left pins on the diagnostic connector under the fuse panel. Disconnect the ISC plug and put a 0.75mm feeler between the throttle and stop tab and adjust it to your requirements...+- 50rpm from 700RPM.
Cheers............ |

Okay. So what knob or suchlike are you actually adjusting? Or are you saying that at a set time during the 'self test' phase the computer will lock in the current operating rpm, and take that thereafter as the idle speed? |
