This isn't that simple. There is an issue with the spark reference circuit. I have attached a flow chart for checks as well as the wiring schematic. I hope it helps.

I just found out yesterday that I have the same problem with my Buick. I'm trying to figure out what it means. Let me know if you got the problem fixed and how much it cost. Please.
