Hey Mrmiata! How are you doing? things have been going smoothly so I haven't been here since October '12. Would it be the crankshaft position sensor if the check engine light isn't coming on? I did just find someone that posted where exactly that is on the Crossfire but also saw someone else..doing the same thing on a different car and ended up resetting the codes after he installed it *this was a mechanic*. Is that something that has to be done on the Crossfire?
