I just started experiencing the dreaded etm/tps issue. My throttle randomly goes dead, rough/surging idle, and possibly delayed starting. I just bought the car 4 weeks ago with the b4 servo issue. Is it possible for the etm problem to be fixed by swapping the old tps with a contactless one? Or do I have to replace the entire module? If I go the contactless route is it just an easy bolt on installation? Thanks for any help!
