  • Hello, I recently changed my ignition coil pack and "stupidly" reversed the wiring from the module to the coil pack...what a racket the engine made spittin' & a'sputtering. Of course, find the number 1 plug wire and start putting the wires into the marked wire holesof the coil pack. I'm pretty sure GM firing order is 1-3-5 on the right side with #1 being the first plug/cylinder.
  • The 2000 motor has a shallow dish in top of piston and a larger combustion ares in the head, the crank had the timming slot cut in the advance direction app 15 o/o your ECM cannot retard the spark enouth to prevent the spark knock , change crank shaft back to 96 bearings are the same , or change the ECM and under hood wireing harness to the 2000 model or go to the 2000 head and intake and maybe the ECM and harness , problem over.
