Crossfire Failure
HELP!
The throttle on my 1982 "Crossfire Injection" Corvette is stuck full throttle.
Happened while I was driving it, turned out to be a real frightening experience since I could not fully stop the car. I burned up the brakes getting it home.
When I start it now, it starts at full throttle and I am afraid I will seize the engine.
I checked the cables and linkage for the two throttle bodies and everything checks out fine. Nothing sticking, returns to rest normally every time.
Anybody see this before?
Looking for some advice,
Thank you,

I'm a bit confused on your description of what happened. If your throttle cable is working correctly and returning the plates back to idle, how is it staying at full throttle? Either the cable isn't working properly or the plates are sticking because your TBs shafts are wore badly. You may want to have another person there while you work the throttle like normally and the other person watch what is going on. OR you have a giant vacuum leak.
