I have an 04 XG350 that cant get out of its own way(2500-3000 rpm no more)no power.been scanned with my sapon scanner and also by hyundai dealership and got same thing,NO CODES!
So i changed the apps and tpsalso ets motor and throttle body no change.cleaned maf just because,no change .today changed ecmand reinitialized still no change .not sure what else to do and hyundai doesnt have a clue either.maybe its just time for it to have an unfortunate electrical fire.
