What is the misfire code on a Buick 3800?

The Check Engine light should be on, and there should be one or more misfire codes for the cylinders that are misfiring. The last digit on a misfire code indicates the cylinder number. A code P0302, for example, would tell you cylinder #2 is misfiring. Chances are the misfire is due to a weak ignition coil.

Why does my GM 3.8L V6 have a misfire code?

Troubleshooting a misfire condition or misfire codes (OBD II) on your GM 3.8L V6 equipped vehicle (Buick, Chevy, Olds, Pontiac) can be quite a challenge. Why? Because so many different things can cause a misfire (also known as an engine miss or ‘dead’ cylinder).
