Upon warm up, my RPM increases to 2000. Not a big deal cause my car just warms up and then goes on the track. I would like to fix it though. I've reviewed the instructions and tried to assure - "Keep sensor wiring away from high voltage or “noisy/dirty” components and wiring, especially secondary ignition wiring (plug wires), ignition boxes and associated wiring." I have the Avenger 4BBL TBI with MSD CDI box hooked up per tach out. Please help me chase this down with things to look at.
