i checked this out on my girl's 98, the code is p1351 "ignition control circuit high voltage/open). she said it stuttered once on her way to my house on a hill, and may have backfired the other day. the plugs and wires are new, however i didnt check the gap on them before installing. i cleaned the maf and tb just in case, and there are some other new items including o2 sensors, fuel filter, and headers. im wondering if maybe one of the plugs is gapped too far out or is defective? it came up once before and i wiggled the the wires to the coil pack and had her clear the code, and it didnt come back until today. i did have the wireing connector off to remove the coil pack to repair a leaking valve cover gasket.

 

On a 3.8 or 5.7?

 

3.8. It's my car.

 

may be just a bad connection. have a look and see what u can find.

 

He thinks (and I think too) that he pinpointed the problem. The wires going into the coil pack or something like that are loose. She actually stalled out on me last night (and automatics are NOT suppose to 'stall'!). So he's going to take it apart today I think and check all the wires well and go from there.

 

So this is what we found. Should be the problem.

 

hey gorn, you are all knowing. do you know where i can get a replcement pin for the gm weatherpack? i know where to get the tools to crimp them, just not the actual pin
