Misfire Cylinder 6 (P0300/P0306)


Recommended Posts

Hey guys I have a MY00 996 Tip with 38k miles. I just took the car out of storage two weeks ago. This morning after having the car sit in the garage for a week (35 degrees outside) at startup I notice a ping/pop sound while idling. Also the check engine light blinked a few times and went away. So I drive to work anyway. Once I get to work roughly 16miles of a drive, I remembered I had my OBDII reader in car (real basic one). I pulled two codes P0300 & P0306 (misfire/cylinder 6).

Now after doing quick searches I find out it may be a cracked coil?

What are the chances my spark plugs need to be replaced? I planned on changing them soon.

Not sure what next steps are? Due to tough economic times, can't really afford to spend too much money. I greatly appreciate everyones assistance.

Coil pack part number? Price(s)?

Spark Plug part number? Price(s)?

Thanks!

I had the same issue and same code P0306 (cylinder #6 misfiring) a few weeks back. I'm sure all your paks are probably cracking, but this is the first one to go on you. You can change out just the one that is currently fouled for 50 bucks. Very easy to do it yourself with the Spark Plug Change DIY write up that Loren posted. Or, you could do what i did and buy all six of them from Oklahoma foreign for 150 bucks. They are a salvage company that pulls parts from low mileage 911s and such. All 6 i bought were in perfect condition and will last a long time. At $25 a piece I figured it was worth it.

Were you able to clearly see a crack in the coilpack(s)? Before you decided to replace them?

Also who did you deal with at Oklahoma Foreign? I may decide the same route, since I don't plan on keeping the car more than one/two yrs. What plugs did you buy?

Plugs were only 20k miles old, so i didn't bother replacing them yet. I think Matt and Gary runs things in OK Foreign. And as far as seeing the cracks, no you can't really see them until you pull off the side engine tin(2 bolts very easy) and then you can very easily see the #6 coil pak. The plastic casing will have cracks and then the inside metal starts to rust.

you could damage the cat, i believe that is what the code warns against. So I would get it to where you can do the repairs and not drive it until you get your parts. The numbers? No, but you can search and find them. Pelican Parts has them 997-602-107-00-M47 for $60..which is i guess the newest version of these paks seeing the 997 number. But if you get them from Oklahoma you don't need the part numbers just give them the year of your 911 and they will pull them from a similar model year.

Hi,

I had the same problem before at 61 000.

I changed all my spark plugs hoping it would go away. After changing all spark plugs I got more missfire codes from two more cylinders. The problem is that there is not much room to change the coils, so you have to twist them a little, and if they are old ones they crack and cause more problems.

After buying all new coil packs ($60 a piece) I didn't have any problems.
