Really trying to help out a friend at work who doesn't need to dump all her cash on trying to solve the problem (poor college student). Car is an '86 Taurus with 3.0L/auto combo. Anyways, the car has a very erratic idle and stalls out sometimes when coming to a stop. She also complains that when she "floors it" it will barely go, I haven't been able to witness this one myself. I figured it would be the IAC but pulled it off and it looked fine, used some carb cleaner anyways to make sure. WHen you unplug it while the car is running, it'll stall out for sure so I'm thinking its working.....whether its working right I don't know. My neighbor is supposed to be borrowing a snap-on scanner from work so I hope to see whats going on. No codes have been set. Looking for some ideas before taking the replace many working parts in an attempt to find the non-working one. Any tips would be much appreciated.
