I have a 2008 grandprix rough idol , accelerating
without touching gas pedal while it is doing this
you can tough the gas pedal and it doesn't work
accelerates up to 50 Mpr , reduced engine power
comes on engine light on all the time have replaced
the pedal 3x and just changed the throttle body
neither have solved the problem this is what the
code said was wrong
Post the 4 digit code or codes you are getting. did you clear them once the parts were replaced and they are back?
