he he, you had a probe…my buddy’s ram got probed once!!! it may be your throttle cable sticking above the intake manifold…check out the whole cable and the pedal assembly.
That happened to me once…I greased the throttle plate with WD40 at every pivot point I could find. Problem solved for now.
It was pretty violent for me. The throttle stuck wide open. Before I realized it was stuck, I shifted; and when in neutral, the rpm’s rocketed to redline and just sat there bouncing off the rev limiter. I’m glad it was a cheap, easy fix!
