So ill try and keep this short and sweet. I had my car tuned a while back and everything ran great, then recently the set screw somehow vibrated out for the idle on the throttle body. So it began driving like **** and backfiring along with inconsistent power. I got a new set screw once I found out and set the idle to .51 volts and the WOT is still in the same place as far as I know, 4.9 volts. But it is still doing the same thing, any clue what it could be?
