weird stuff with my 93 vert automatic; sudden pulse, high rev in neutral

"Chicks dig me and guys think I'm cool."

So my wife and I are going for a drive in the country in the 93 convertible with auto tranny. I was coming up on a light and noticed the car was still accelerating, even though I pulled my foot from the pedal. I thought the pedal might be stuck, so I put my foot under it and pulled backwards, but the car kept revving higher and accelerating faster. I then put the car in neutral, and the rpms jumped immediately to around 5500. Fortunately the light turned green and as I made my way through it I put the car immediately back into drive.

When I did this, the car seemed to lose power....not electrical power but drive power. I told my wife "well, maybe we can limp home like this" and as soon as I said it everything went back to normal, and we made the last mile to our house no problem.

I'm thinking two things that come to mind; first perhaps the TCM (transmission control module) went on the fritz. Secondly, I thought maybe the gas cable somehow became stuck, then unstuck, then snapped back into place.

Thoughts?? :hmm

the automatics have a dual cable, one side goes to the throttle, the other side goes to the kick down on the transmission. check both ends.

I failed to mention that the gas pedal has a little stick to it. Sometimes I have to give it a bit more of a push to pop it. So t3ragtop, you think one of the cables to the transmission may have stuck?

I've had the kickdown side cable fray and get stuck but not affect the throttle. But I would check the throttle side for sure though. The tcm would not cause the acceleration you spoke of.
