Hey now I maybe young but I have always done everything on the cars I have owned. Two transmissions went into a chrysler cirrus with these hands! Thus far everything about the crossfire has been easy this is the first time I have run into a time consuming job with the car yet. I have taken the coil packs off but even still my mittens are to big to fit down in beside the heat shield. I will be giving it another go next weekend. I to much going on to attempt this week or weekend good to hear the power gains were noticable I'm getting some rough idle at higher temps I'm hoping this solves the issue otherwise I'm at a loss...
