Got some strange issues with my puma converted zetec-s and wondering if any of you have any idea on whats wrong with it.
So far I've tried replacing the ICV, TB and TPS, MAF, twice each (One from a working car and 2nd they were new). Also couldn't find any air leaks.
PAS Pressure switch is unplugged as I've removed the PAS pump etc.
Inlet is a LMS item but had tried using the standard inlet to no avail.
Unfortunately because the car is off-road and not insured/taxed I can't take it to see if any fault codes are present on the ECU (TAPE).
1. When started the car will idle at 3-4k.
2. Press the clutch down, revs drop to about 1.5k and you can rev the car as normal etc until the clutch is back up and its shoots back to 3-4k.
3. Unplug the MAF, car idles mostly ok (Little unsteady on the revs - fluctuates by about 50-100rpm) and revs will hang if you use the accelerator (Back to 3-4k) until the clutch is down.
From what I've read the clutch being depressed and the car idling more normal is the opposite to the problem most encounter.
If anyone has any ideas or suggestions they will be most appreciated.
If any more info is needed please ask and I'll update anything else if i remember anything else and will try and get a few videos at the weekend if it would help.
Regards,
Dan.
