big problem not a clue ok i have a bit of a problem.my f'n car went crazy i was working on it putting some cosmetic stuff on it and the battery went dead. no big deal right well the last time that happened the same thing happened but for whatever reason it corrected itself well not this time.heres the deal.i thought i had a tps problem so i put on a new one.charged the battery and the car fired right up.drove it for about ten minutes or so stopped ran into the store came out started right up drove to a friends parked it and about ten minutes later went to move it and the crap hit the fan i start the car and it's fine i wack the throttle cause my buddy had'nt heard the car with the dump open.well when i did that the rpms stuck at 3500 rpm's.
now i have checked the obvious so now i'm lost and if this will help at all the headers after a few minutes were glowing red *** hot and i know for a fact that is not normal and is certainly not good way to lean.i have a vacum tranny and have checked the vacum line and its fine so i'm out of ideas now bear in mind that this has happened once befor but the car corrected it's self so i'm lost any help would be good any at all i will check whatever again if i have to thanks in advance..............darrell

My car does the same thing every once in a while, except I don't get header glow. Mine started doing it before my header install, so that may not be your problem. Also, I've noticed that the last time it did it I had the defroster on and when I turned the defroster off, the idle came right back to where it's supposed to be. Also if I leave the car alone for a few seconds the idle will come back down from 3500 rpm and after a 40 seconds act normal again.

Verdad Gallardo I wonder if your IAC is just sticking or something. I don't think that would explain the glowing headers though. Try unplugging your IAC when your car's idling low, then when it's unplugged see if you can reproduce the 3500 rpm hanging problem. It's too bad you don't have a scan tool, it would help a ton.
a huge vacuum leak somewhere? I would pull off the front of the air tract and put a book onto the throttle body when the car is running and see if it still runs. 
that would prove the big leak you have if it still runs with the throttle blade pluged up... 3500rpms is a pretty big leak.....
