idle air controler. The ECU can affect timing to control idle under certain situations. Every one here is trying to help. Your coming up with reasons why we shouldn't.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

its not a vac line it would do it all the time..

wrong, not all vac lines are direct fed from the crank case.  some are solenoid operated so therefore if the predetermined time in which the solenoid should/should not get power drives the fact if the vac line is either on line or not.

what are the codes?
what is the fuel presure while driving and during transmission shifts
is the inside of the FPR vac line damp?

a fuel pump acting up can also cause these symptoms and the only thing that may trigger a code is if for some reason you see various lean/rich codes on injectors.


get a couple cans of carb cleaner like mentioned and waste them along the vac lines and along the intake as well as underside.

it sounds like your not really familiar with this era of fords, takes some getting use to to realize they are not all that complicated.

the only codes it had when i pulled the coeds was for the map, egr, and 2 to do somthing with the emitions.

Next time it does it.  Leave it running and give the IAC a firm thunk with the back of the screwdriver.  If it drops back down to normal, you need to clean your IAC.

If you un-plug it does it settle back down to the base idle?

just so you know, the map sensor basically makes the car run. If the vacuum line is pulled off, your car thinks that it always has no vacuum and will throw all the gas at it that it can trying to keep the car running.

Either that vacuum line is bad, or your sensor is screwed or you have a broken wire. MAP=car running.

Run codes, write them down, then tell us what they are.

I drove for almost 1 year with no thermostat.  Well a lack of thermostat would be a better way to put it. Car never got  over two bars on the digi dash. Old thermostat was rusted out and was  dug out of the lower intake in pieces. The car would just always think  its running cold, because it was. I don't see what that would do with  high idle?

 
 No, not to ~3000, but I have seen with my own eyes my bud's s-10 that  would constantly idle ~8-900, and we could never figure out why. One  day, he decides its time swap out a couple of nasty looking rad hoses,  pops one off, no tstat! So, put one in, and now idles down where it  should be.
 
 We figured maybe it was because it always thought it was cold, so it was  confused, running richer and causing rpm's to go up so it could warm up  faster.

mine cuts off completely if I do that heh heh

but it was giving me problems too when I first got the car. I took it off and sprayed wd40 inside to clean it out (cause I was fresh outta carb cleaner) and that made all well again. course it only lasted a few weeks. did that about 3 more times, and just went out and bought a new one!

yeah, the line that runs to mine started to rot out about a year ago, took me forever what was causing it to act up, but when I found that, problem solved.

And if you detach it... oh boy.........
