Today I was driving my car on the highway and it wanted to drive itself. By driving itself I mean the RPM's stayed up around 4500. The RPM seemed to rise a little when I put the clutch in. Is that what the THFix is for or do I have another problem? This happens quite often, mostly rpms stay around 2000, stopped at light. And between 3000 and 4500 between shifts. Any help would be greatly appreciated. Thank you.
