Here is the next part of the puzzle, car has been at the shop about a month. So far everything suggested has been done. The computer still has a crank sensor code,,,,tech removed the MAF and cleaned the throttle body and now the car which never had an idle speed issue has a severely high idle which can not be reduced. Also I'm told that when carb cleaner is introduced near intake manifold passenger side of engine the rough performance stops. Any ideas?
