Hi everyone, I'm experiencing a rough idle on my boxster. I hooked up the Durametric and I have the following codes:
P code 174
P code 62
P code 65 cyl 3 misfire
P code 63 cyl 1 misfire
P code 64 cyl 2 misfire.
I had a misfire on a single cylinder a year or more ago and it was a hairline crack in a coil-pack. Any ideas what would cause 3 cyl. to miss all at once?
I only replaced the 2 worse coil-packs last time. But its been running great until recently. I replaced the CPS which cured my hot-starting issues. The roughness seems to smooth out with increased rpm's although Its probably just less noticeable.
Any input greatly appreciated.
Thanks,
Garry
