Ok, we’ve got an auto EA with an I6 engine here doing some weird things with idling. When you place the car in park or neutral and give it a rev the revs build up, but then drop below its normal idle speed to a point where the car nearly stalls before picking back up to idle again. It does not appear to be temperature dependant.

I had the same problem with a Holden VK once and I solved it by adjusting the base idle and fuel mixture on the carby, but a Ford EA is a far cry from a Holden VK. So what do you all think could be causing this?

Thanx in advance,
Defective User.

Is it CFI or MPFI?

Ok first try setting the base idle ( do a search for "base idle" for the procedure )

Next I would be checking the ISC and TPS

Ye, srry, 3.9 CFI... Ill check that out... any other ideas? BTW: Do the CFI's even have an ISC?

yep but its a stepper motor which basically follows the throttle lever up and then when you lift your foot off the pedal the motor will bring the lever down smoothly and to the correct position. if its not working then the throttle will drop suddenly and almost stall
