Completely baffled, more and more codes...ECM issue?
From my last thread , I thought I'd clean out the throttle body to start and see what would change...I no longer get "Engine Systems Error", but now I'm getting a misfire causing a very rough idle. And more codes for the throttle and pedals (?). There's nothing wrong with the battery and I doubt there's anything wrong with the throttle systems either...in any case, that wouldn't case a misfire. Anyone have any clue what's going on?
