XKR idle surge
I have finally got most of the bugs out of my 2001 XKR except for the idle. It runs fine off idle, but Idles like a 350 chevy with a 3/4 cam. It lopes enough to make the car rock at stop lights. I have checked all over for air/ vacuum leaks and checked the mass air sensor. I cleaned the throttle body, but it still the same thing. I have not checked the crank position sensor yet. Is there a programming setting that needs to be done or is this a mechanical problem I have missed? thanks for reading this steve

OK, guys, I found a vacuum leak between the supercharger and the inter-cooler. redid the connection and the car smoothed out. I was under the impression that area was a positive pressure, but it really is negative pressure until the motor comes off idle. Thanks for your input. It is wonderful to have this forum with all the great people. steve
