update

Only happened once since my last post but throttle was working if I shifted into neutral. Just not a single response in drive. And I would love a little help. ANYBODY?

get a good scanner on it, guarantee there is a code of some sort, a lot of codes will not trip the CEL

Im using the innova 3130c. No codes.

It may be your throttle position sensor, just a guess not sure how to trouble shoot
