I'm thinking some things you have to write off as a glitch.. Wife's car exhibited throttle position sensor syndrome.. Passed a vehicle on our rural path and next thing it "seemed" it was taking more pedal than normal to maintain speed.. At the stop sign to the highway .. acceleration was almost non existent. Limped it the half mile into town.. pulled in to station parking lot.. turned off.. turned back on.. and haven't had an issue since and that was about a year ago.

So basically.. see if it will do it again.. LOL
