Thank you all who responded. I'm the second owner to the X-Fire. The first owner apparently swapped out the regular engine and replaced it with the SRT engine. The six speed transmission with the SRT engine makes for an awesome combination. The only problem is how quickly it reaches redline. It is too bad that MB did not make that a combination from the factory. I bought the car from a dealer that did not know what the Crossfire was, which worked out for me and the dealer had no clue of the SRT engine under the hood. I did find paperwork in the glove compartment that the previous owner had sent the XFire to Ren Tech Motorsports in Florida to have the car fine tuned at a cost of over $8 K. So I have a great fun sport car, BUT I need to resolve the problem with all the idiot lights being on.and a non working wing and convertible top, and no brake lights! So looking for help to resolve this!
