I have a 2001 Camaro 3.8 that is running really bad. The fault code shows P0300 multiple cylinder misfire. I have changed plugs, plug wires, air filter, fuel filter, mass airflow sensor, and EGR Valve with no effect. Has anyone else had the same problem and if so, what fixed the problem.

Try disconnection the MAF sensor. Let us know if it runs better.

 

Sounds like you may have a problem with your coils or the board circuit board.

How do the plugs look?

 

Did you ever figure it out?
