sorry i took so long to reply but i got sick yesterday. i checked for vacuum leaks by spraying carb cleaner and listening for an idle change. i guess i will check the all the vacuum lines and intake areas again especially the EGR vacuum (from the pulled EEC code). is there a location where i should concentrate my efforts towards. thanks again guys for all your input.

 

u should probably take it to an experienced mechanic tell him all of what you've tried and have him have a go at it, i mean you've probably exhausted the otions a home mechanic can use its time for you to shell out a cuople of bucks and hopefully you can enlighten us with the results so we can understand what the problem is.. i'm dyin to know what the deal is now.

 

throwing in the towel...taking to shop on wed...i will let you know what the verdict is

 

I have a semilar problem. SOmetimes my RPM's will shoot up to about 1500-1700RPM but If I shut off the engine and restart it, it idles normal. Is this a vacuum leak?

 

well i took it in to a local shot and they worked on it for 2.5 hours with no result so i guess i am going to take it to ford. someone suggested to me the fuel filter could be bad so i will probably change that for giggles to see if it works. i will let you guys know when its fixed.

 

the weather in nor cal finally lightened up so i took the car to ford. they said the iac needed to be replaced and the fuel injectors needed to be cleaned. i replaced the iac and the fuel filter and the thing runs like a charm now. the only thing i am left to wonder is how the iac passed the test in the manual but not at ford?
