When I experience loss of power, if I smack the dash just passenger side of center, it will correct itself for a while. It was by accident I found this but I have done it numerous times and result is immediate, whereas if I do not hit the dash it stays at lost power. I don't have much money right now, so my donation is small, but I appreciate any help I can get. Thank you.

No codes. The comp is at foot of passenger side and was replaced about a year ago. I am thinking it's gotta be a short of some kind. Something loose, it feels like if an injector were clogged and when I hit the dash unclog feeling... I know they're different issues, just trying to describe the feeling....
