Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi There, I'm Clayso a certified master automobile technician with 30 years of automotive repair and diagnostic experience.
From your description most likely the Ignition Control Module (ICM) is to blame for the miss since the plugs and wires have been replaced. I would be very interested in knowing what code(s) are set before throwing an ICM at a problem and hoping for a fix. Anytime the check engine light comes on Diagnostic Trouble Codes (DTC)'s are stored in the Powertrain Control Module (PCM). See if any parts stores in your area will check the vehicle for codes, if so let me know the specific P codes stored before throwing an ICM at and hoping.
Let me know.Thanks.
