I was driving my 87 td wagon the other day, and the gas pedal started to sink to the floor and the car started accelerating (relatively slowly). I hit the brake, and the pedal popped back up. This has happened a few times more since then. I think it must be the cruise control, since pushing the cruise control stick forward also causes the pedal to pop back up.

I had never tried the cruise control before, but I think it probably never worked. It doesn't do anything now, unless this problem is happening.

This is obviously unacceptable, especially since my 16 year old daughter drives the car. I don't really care about the cruise control. If I just unplug the amplifier will it disable the system?

Is there some sort of throttle actuator that I can physically disconnect, or does it work via the electrical connection to the injection pump?

Thanks for any input..
