The Crossfire is not as user friendly has say your 01 Camaro, or the Vette. I did the same thing to my Silverado. You can't screw around with the these Sensors, they are way to sensitive. The other thing in addition, is Mercedes Electrical system Sucks. I mean it fluctuates like crazy when just in Idle. The alternators are about as useful as a paper weight, and a lot of the Key components that should have a direct connect set up, are all looped in with like three different Access. I would be stoked if someone would pull out the electrical system, and re-do it the right way. It may be just me, but every American car that I owned, I have never had these kinds of issues. It maybe acceptable in Germany, but isn't acceptable in my house.
