I would get it to the dealer honestly. When i had the repeated misfire on my #4 cylinder along with blinking check engine light I ended up with a new engine in my 996. Good luck.

Damn, good for you. That's hilarious. I didn't even catch it the first time. This could be PAG's new slogan:

"Buy a Porsche and all your problems will be behind you."

Funny...

Tippy

I don't care who you are that there's funny!

Like everyone else suggested, get the codes read, it will tell you more or less where the problem is.

My '99 996 w/ 67,000 miles had issues very similar to yours. Whenever I turned off the motor and restarted it (groceries, gas station, post office, overnight at home), it would idle like an aircooled VW . Blip the gas pedal and it clears up. 4 days ago, check engine light came on. Tested at my local mechanic and cyclinder 3 had an issue. Coils bad. Ordered the part set the appointment date, and a day later, steamed up, overheated, DEAD!!!!!!!!!! Catastrophic failure. Now I'm deciding on whether to put a new 3.4, a used 3.4, (or does a 3.6 fit in there?). As it turns out, in retrospect, maybe the head gasket was going bad. Either way, it was just a matter of time.
Car has had no issues. Had several DE events at CMP, one at VIR. Darn, I wasn't even ******* it when it died on me.

Sorry to hear about your loss! That sucks.

A 3.6L engine will fit, but there are other things that need to be changed/adjusted. Paul 996 recently replaced his 3.4 with a 3.6. Here is a link to his thread which will give you some info.

Replaced 3.4 engine with a 3.6 engine

Whizbyu,
Sorry to hear the bad news. Hope the rebuild/replace works out for you. Please keep me/us posted.
Best wishes,

Tim, saw your same advice on a different thread. After 8,000 you just issue standard replies?

gota911

Well, I answered his question here first, and then I noticed he had started his own thread asking the same question. I wasn't sure if he would come back to this thread and see the link, so I figured since his question was repeated, I could repeat the answer.

Once I hit 9,000 posts, all of my posts will be one of the following 4 replies:

1) WTF? Where are the !@#$%^&* pics!
2) DAFS!!
3) RTFM!!
4)

I think that should cover 99.87% of all topics and I'll just ignore the remaining 0.13% of the topics!

You are blessed with a keen sense of humor. Keep 'em coming.

So what did your mechanic say??

This same discussion has been going on over on the 996TT forum....unexplained electrical gremlins that cause random misfires. You turn off the ignition, turn it back on, the CEL is gone and so is the problem.

Several guys have had this problem (me too). I finally sent it in to the dealership and they replaced the MAF under the CPO warranty. You can also go to AutoZone and borrow their reader....just take it outside and plug it into your car, read the codes, then give it back to them. The turbo guys are more prone to do the start/stop/start routine without worrying about catastrophic failures like some of the My99-00 3.4 litre guys.....There are a number of recurring issues that have surfaced for the 3.4 litre including the intermix issue, intermediate shaft, and pourous cylinders that seem to hit without warning and are not related to hard driving or abuse.... so ignoring the flashing CEL light like some of the TT guys have been doing might be ill advised.

Ouch! After the coil went bad, about how many miles did you drive before the engine blew up?
