[font=Courier][color=blue][b]I had the same problem, here is what was wrong. I replaced my spark plugs at 75,000 miles with the ones that GM recommends. I had problems with starting and rough idleing. Here is what the dealership came up with
Bad Spark Plug wires
Rotten Iginition Coils
After replacing that the car starts great and runs very smooth. so maybe have it checked out. Cost like $80.00 for a Diagnostic Check like what was done on my car.
Now i have the famous Intake Manifold Gasket leak!!!!!!
