well today im driving around, i give the fd lil gas maybe go to 3 pounds of boost, then i let off, and the throttle sticks for a split second. then it the revs drop to 1000 rpm, then proceed to rev from 1000 to 3000 rpms, as if the car was lobing. so i pull over because i dont know wut it is. all i can think of is that its something with the ecu, so i disconnect the battery for a few minutes and when i reconnect the battery adn start the car..... the revs jump the 7000 rpm's and hold without my food on the gas..... so obviously i just turned the car back off..

but does anyone know wut could be causing this problem? any insight would be greatly appreciated

A while back I had the EXACT same problem. It turned out to be the cruise control. If you pop off the black cover on the cruise control unit, look at the cruise control cable, you'll see how theres a black cover over the cable. At the end of the black cover where the cable goes into the unit, you'll see the cover is crimped. Make sure it didn't come out where it was crimped. If it did, just shove it back in and check to see if it fixes the problem. You can glue it in or just re crimp it if possible.

Edit: It only takes a few secs to check so report back, if thats not the issue, I can post up some other things to check.

Well, since you mentioned something about the throttle sticking, look at the throttle cable. Make sure that the cable is hooked on all the clips. Also look at the TB, one of the springs or something may be keeping the buttery fly valves open. You also may want to make sure the MAP sensor, labeled Boost Sensor, located against the firewall, on the drive side. Make sure the hose didn't pop off on anywhere. Usually if its disconnected somewhere, it'll create an irratic idle, but i've never heard of it causing the car to jump to 7000 rpms upon start up. Thats about all I can think of, but i'm sure others will chime in during the morning. Also try searching around for your problems.

Also consider doing a TPS readjustment. IIRC that can cause wild rpm issues.

Yeah, none of the electronic systems on the car (ISC, AWS) can get the idle up THAT high. The only way is some sort of mechanical problem with the throttle body or with the throttle or cruise control cables.

Pull the TB elbow off - it will be obvious if the throttle is wide open. Then start looking for what's jamming up the works.
