I have a 1985 Jeep Cherokee, 2.8L V6, and it accelarates sometimes when I'm on the road without pushing the gas pedal. I have to brake frequently because I'm afraid of hiting the car in front of me. Can it have something to do with the cruise control?

I would first disconnect the cruise control cable

Then check for a broken motor mount.

Make sure the ign. timing is set correctly.

Then check to see if the idle kicker settings are correct.

You should also check to see that the choke is not closing partially and putting the fast idle cam in play.

I have also seen the throttle shafts wear and stick open slightly and intermittantly.

tps dude, throttle position sensor. its prolly bad. and you shouldnt be driving that thing till you get this problem taken care of.
