05 avalanche loosing acceleration and dash goes nuts?
So i have been searching threads but cant find someone with this issue. While driving ( this has happened a couple times) i would loose acceleration and all the warning lights would come on, stereo turn off for a second or two then i go off like nothing is wrong. Anyone have an idea as to what this cluld be? I do have my knock sensor codes on to where i have replaced both sensors, the wire harness and the ecu and cant make it go away. Still reasearching that one so any suggestions there would help too.
