Hi guys my 2000 grandprix seems to be missing at around 2000 rpm. It seems like a spark problem.I have changed the plugs and wires and 1 coil. But the problem still there. The engine light don't come on. Could it be the egr valve. But I would think the engine light would come on if it were acting up. Or do you think it's the ignition module acting up. Do you have any suggestions. Thanks in advanced john

You can have the ign. Module tested at most autoparts stores for free.

Check spark on each plug with spark tester, look for snapping blue spark, anything else is considered no spark.

Check spark plug wires for cracks or burn marks.
