2 days ago when I first got in the car, it wouldn’t accelerate over 50 mph. I pulled over, turned off the car, waited 15 seconds & restarted it. It was fine after that & I didn’t have any problems yesterday. What happened? ---

It was fine after that & I didn’t have any problems yesterday. What happened? Your Ask Someone question has been redirected to a/the Car Talk forum, so welcome… Was the CEL on and what are the codes, history, pending and permanent??? Was the engine revving way up if the transmission was slipping, or was it bogging down or simply would not rev over X rpms, or go over 50 mph?? Please explain in more detail what happened… ---

On the outside chance that Robert will actually know where his post was moved to . You have a warranty at least have the dealer look at it so the problem will be on the record if it happens again.
