Post subject: throttle body messing up
04 tiburon v6 2.7l. alright so my car revs up sometimes without me pressing the gas. i have to step on the gas hard for the rpms to go back down. i think it could have something to do with the butterfly in the throttle body that its not closing right and it just sucks in air and starts reving up pretty high. is my spring too lose that pulls the throttle cable back?

More llkely, especially if you have a 1.8 or 2.0 engine, is that the
throttle position sensor is malfunctioning. Also check for vacuum leaks
at the PCV hose and the intake manifold gasket.
