My problem,going down the road idle goes high stuck lucky I made it home a mile away.peddle not doing anything ,in neutral still high.Took off idle accuator ran still high.any suggestions?1991 Ramcharger 360motor.just rebuilt throttlebody all gaskets intake &manifold.

 

either you have a cable stuck, or a vacuum leak can also cause high idle. might aslo take the thottle position sensor off and make sure its till good and the spring didnt pop in it.
