clean your fuel injectors, once you cleaned them, use the highest octane fuel and take it on freeway burn the carbon deposits that is accumulated on valves, use high octane once or twice in a row to burn the carbon off, then switch back to regular, I usually manage to put in at least once a month high octane to clean my system.

 

Will the car rev freely in neutral?
