I had the same symptoms (misfires and flashing CEL) and it turned out to be bad gas.

Leading evidence: 'gas' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'gas' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check each coil pack as he' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I have not lost a MAF, but when the filter does need changing (which incidentally will not be for around 40K miles), then I'll switch to one of the dryflow filters.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

so i start up my car to take it to the u-wash. idle seemed a bit off, kind of rough.
i put it in gear and, holy sh*t!
, a steady CEL. idle is rougher. i turn off the car, wait a minute, and start it up again. now it's a flashing CEL! *fargin-a!*
of course, i immediately check the garage floor. some water from the weather, but no oil.
i call over to my trusty indy and he can take my car. i start it up again and it's a solid CEL. idle is rough. i limp it over to the shop. it is the longest 6 miles i've ever driven. car is obviously misfiring.
get over to the shop and code reader shows:
P0300, P0306, P0301, P0305. basically misfires on cylinders 1, 5, and 6. cat damage warning.
my mechanic checks for loose vacuum lines prior to putting it on the code reader, there are none that are obvious.
he's thinking cracked coil packs or bad plugs (i haven't gotten new plugs yet for my 60k service). but it doesn't seem to be anything major *cross fingers*.
he'll call later this afternoon or tomorrow morning when he get's a chance to pull the plugs on the misfiring cylinders.
now all i can do is wait, but i'm optimistic.
When did you last put gas in? I had the same symptoms (misfires and flashing CEL) and it turned out to be bad gas. Not Taco Bell either. Turns out that when the big tankers fill the underground tanks they can stir up crap, water, etc in the tanks. This can get into YOUR gas tank and cause minor heart burn until you run the tank empty and put fresh petrol in.

hmm. last weekend at a mobile station and my tank is still at least 3/4 full. i guess i'll find out when the mechanic gets to look at the plugs and coil pack.
90% it's the Coil packs, same with mine last year. Might as well do plugs while you're there
Technically it's a DIY if you have skinny fingers and/or nice angled tools, I'm pretty sure there's one on Loren's site
I'm just waiting for my MAF to go. The techs at the indy think that the EVO CAI on the car is a recipe for a very short-lived MAF. So far though, it seems to have survived a few thousand miles without getting sick.
Hopefully the shop will take car of the OP's problem with no problems.
Why wouldn't you remove the EVO CAI if your indy makes that statement?
I have yet to understand why anyone would put an oiled air filter in a Porsche in spite of the numerous comments about the oil killing MAF sensor. Makes no sense to me to risk that damage to get some additional intake sound and a handful (if any) HP gain.
They said that since it was already on there, that the damage was probably done and that there was no point in putting the stock air box back on until the MAF gave up the ghost. I did make sure to get the stock intake parts from the PO as part of the sale. I hear the MAF is a DIY job, so I was contemplating doing it when it goes.
I had some reservations about the mod, but the PO seemed to think that the EVO version was better than the K&N as far as MAF issues go. Still, I see plently of folks on 6speed buying them (and many uninstalling immediately after).
You think I can avoid the MAF replacement by swapping the stock stuff back in after 2k miles with the EVO?
Could I get a second set of eye on this:

How can you tell if it is an oil filter? Seems like the only indication is that they offer some K&N cleaning products...
What about these filters?

Appologies to the OP - I'll bugger off onto my own thread on this if need be.
I have an Evo intake. I love the sound and would never go back to the stock airbox.
I have not lost a MAF, but when the filter does need changing (which incidentally will not be for around 40K miles), then I'll switch to one of the dryflow filters.
yep. got the car back. just bad spark plugs. i got one of the bad ones from cylinder #1. contact point was square and concave from wear. to anyone else considering holding off on spark plug replacement: don't. it'll save yourself some premature gray hairs.
anyway, car checked out fine. pulls strong. funny thing is is that it pulled strong right up until plug failure. it's like switch got cut.
anyway, whole bill was about $200 including 6 new plugs.
