DanG,
The wires are brand new. The main reason for copper plugs would be that I do run Nitrous in the car or I should say will be once it is running right. The TPS is calibrated correctly. The MAF is calibrated for 24 pound injectors and was custom done for the car. I am running 19 pound injectors as of today because the 24's that I have seem to have bad seals on them. I would think that with the 19's in there the car should still run ok as I had this same problem even with the 24's.
