Default serious idle problem, help needed asap please!!!

i was comming home yesterday on bristol and i went to slow down, cars stopped in front of me at the light and my rpms jumped up to 3 grand and stayed there.
my car would NOT stop, i was standing on my brake and shes lurching forward, thank god i have a line lock or i wouldve hit someone. i put her in park and it stayed at 3 grand, NUETRAL - FIVE grand. WTF is wrong?? i checked everything i could think of and i cant find anything wrong with it. i limped her home and went out last night to check her and shes fine now, but im scared to drive it.


ideas?






edit - i need to move this from the western section, sorry

If it happens again don't just stand on the brakes and hope it stops, put it in neutral then depress the brakes normally. Just a thought though.

I just had someone tell me about the same problem. Did the computer throw any codes? i.e. SES light on?

throttle cable might have been stuck, as in a rock something, could also be an IAC solinoid but it will throw a ses code, or u have a big *** vacumm leak after the throttle body. first i would do is remove the intake and check out if the throttle body is moving freely and i would clean it with some throttle body cleaner.

in my eXperience...if im in 6th and im barely tapping on the gas, the accelerator gets stuck...i dunno if its the cable or what...but sometimes it even accelerates like ur flooring it, but the pedal it FN stuck...I mean...it only happens once in a blue moon, but it does happen...i dont really have a for sure explaination why, i can only tell u what happens...

No load on the engine in neutral.

well the only way it would idle higher in N is because something IS stuck giving it gas.

Damit brynnda it's either you tb or your cable getting stuck its not an idle issue since your car can't be @ 5k without a significant amount of air going in. Unless you have a heavly ported high performance idle air control valve lol.
