My '05 mc is misfiring after startup the other day, and i just replaced all plugs, wires and coil about 4 months ago. any ideas? taking it to a shop to get a more accurate diagnosis, hopefully. codes right now are p03 (reader won't give last two digits) p2097, and p1477 which comes and goes.

 

What kind of plugs and coil? MSD? I have heard of issues with misfires with them. If you have the old stuff i try to switch to your older coil and check to see what happens, then try the wires. Goodluck and hope that helps alittle.

 

The coil I put in there is a Beck/Arnley ignition coil, and the plugs are NGK (not sure of the model #, but they are for MINI)..wires are made by Denso. Brought it to the shop this morning, I just hope its something simple, I go to college and don't have the time or resources I would back home to work on it and look for any one of the many sensors, wires etc.

 

It turns out it was the ignition coil afterall...i never would have thought it would have failed after only 4 months, but it sure did...cylinder 3 wasn't firing at all. problem solved.
