My cruse control is out of control, I have a 87 GTA, when I set the cruise the peddle goes right to the floor and stays there. Anyone have any ideas how to fix it. thanks

 

pedal goes to floor......sorry i don't see what the problem is ... =P

were you messing around with the cable around the throttle body or CC diaphragm or anything?

 

Sounds like it's of adjustment. When did it start doing this?

Basically, you press the button on the cruise, the computer says "OK DRIVE HERE" and the diaphram on the cc tightens up, pulls the cable/rod tight in order to hold the throttle in position. On some models it's a ball-chain rather than a hard cable or rod (like mine, dumbest design I've ever seen).

Now, there is usually a sensor down on the drive shaft (for older cars like mine) or in the newer cars the sensor is in the dash (I think but only for Electronic Speedo's). Could be that that's going bad/is bad, or your computer that tells it where to set is out of whack. Anyway, that's where I would start. Hope this helps and if I'm wrong, someone who knows please post.
