Guys,

'98 Boxster 5 Speed, 82,000 miles

Among other things, at 41,000 miles (2 1/2 years ago) the car received new fuel filter and new Bosch Platinum 4 plugs in the correct heat range. 41,000 later this is the first issue of this type.

Two weeks ago i overfilled the fuel tank and got an evap cannister CEL and cleared it.

Today the CEL came on so I headed for home to check with Durametric. Just as I pulled onto my street the CEL started to flash and there was hesitation at around 3000 rpm's so I coasted in.

Durametric shows P0300, P0305. P1317, P1319 all misfires (Cylinder #5??).

I searched this site and saw several examples of similar issues. "A leak in the air intake, Connection to the plugs were not plug-in correctly, Need new fuel filter, The platinum plus 4 are not good for the boxster, Coli packs need replacement, Vario-Cam sensors" to name a few.

Any suggestions of where to start as a process of elimination?

Any help greatly appreciated!

Regards,

Clearly the problem is on cylinder 5.

I suggest you inspect the electrical connector, coil and remove and inspect the spark plug on cylinder 5.

Thanks Loren,

Will do and I will also report back as to what I find.

Regards,

Loren

Turned out to be coil pack on #5, I am back on the road and car now runs great. I have 5 more coil packs ordered along with 6 new plugs as it has been 40k since last changed.

Thanks!
