Hey guys.

So I was out on a drive in the 986 recently, as I was pulling up to my drive way my check engine light started flashing I pulled the car into my garage turned it off and scanned on my OBD2.

P0305 (misfire on cylinder 5) I came on the forums and researched what it could be. Most of the answers given said to replace coil packs and spark plugs. I then up the car on jack stands and changed my spark plugs and coils all around.

Problem is still there, i'll turn the car on and the same code comes back. I tried disconnecting my MAF to allow the engine to run without the MAF's assistance and it made no difference. I then checked my coolant and there's no oil in it. My car only has 56250 Miles.

Has anyone had similar problems?

Thanks, Lucas.
