My throttle body gets stuck open while flooring it in wide open throttle , which make the car bounce of the rev limiter. Does anyone know what might be the problem.

 

First off, make sure your floor mat isn't getting stuck on the pedal. If that's not it, then check around the throttle cable on the throttle body to see if it is clear of anything that could be catching on it. If that's good, then get a can of carb cleaner and clean your throttle plates.

 

no it's not getting stuck by the carpet, I clean it tomorrow. thanks
