Although on my 97 PA my CEL flashes 4 times and the chime sounds 4 dings every 10 seconds and the car runs rough and surges, tach bouncing all over. The code came up as CPS circuit A error or something (I'll have to look it up). I replaced it (after having to have to have to tape the holes for the puller, weird huh?) and had the same problem. I was also getting a missfire #3 and since I had already replaced the plugs and wires about 6 months previously I ended up changing the coil pack. The car ran fine for about 35 miles and started doing it again. So I either have a defective CPS, or a break in the wiring for the CPS.
