1999 Boxster 2.5L - Trouble codes for mis-fire - Emission Relevant???
Today I got these codes when scanning the check engine warning. Does anyone has had this happen like this and what you think it could be. Obviosly the chances of all 6 cylinders misfiring at once is pretty slim to none. Perhaps its bad coils and plugs that is throwing the ignition sequence off? Any thoughts or insights?
My car is a 1999 Boxster base manual transmission 2.5L Thanks!

Thanks will post on Boxster Forum as well! I just got the car and tried to smog it in CA but these codes came up. Will check plugs and change coils with correct new plugs later and will post results. Thanks!

This means you haven't done any work and just bought the car?

I'm gonna go out on a limb here and suggest that you got burned - this is based on having lived in California my entire life without having bought or sold a car that didn't pass emissions. The only REAL reason not to do it properly - i.e. as a seller, getting the car smogged up front - is because it won't pass. I could see skipping a smog cert for an old pickup or something, but a Porsche? And a Porsche with an engine design KNOWN to be flawed and tremendously expensive to fix? Nah, I'd have a smog cert as proof that the car is running properly. Unless I couldn't.
I would CAREFULLY document the condition of the car right now, including the condition of the coolant and oil, and explore whether you have any recourse at all with the seller. If this was a private-party, as-is, no warranty sale, I advise you to carefully consider any advice you get from other people here BEFORE you allow anyone to tear into the car and start fixing things.
Also, when the first shop tells you not to worry because it's just a head gasket: It's not just the head gasket.
Sure, it's POSSIBLE that you just have cracked coil packs and they were ALL wet, or crap in the fuel tank, or some other benign and easily curable situation - but then you'd have a coincidence. And there are no coincidences with used cars - just untold stories.
