P0264, 261, 273, 037, 270, 276, 057, 267 became P0277 and 306
Just had to leave my car at a car show (a two day one so I left it for the night). We made it there just fine, but come out to find the car wouldn't start. It was showing all of the codes (P0264, 261, 273, 037, 270, 276, 057, 267). I checked the fuses and the 30A fuse for the fuel injection was blown. Replaced that and cleared the codes. Then I starting getting P0277 and 306 for a misfire on Cyl 6. Cleared the codes multiple times and drove it around a little, but it would never go away. I just had new plugs and coils installed last week. I've put a couple hundred miles on those with no problems before now. We did go through a pretty powerful car wash on our way to the show. I'm trying to get armed with as much info as I can so when I go back tomorrow I can drive it home.

double check connection on coil and make sure spark plug is torqued correctly on 6.
if not spark or coil likely injector. if not a "blinking light" fresh gas and techron.
Lots of threads on single cylinder misfires.
Bore scoring on cold climate cars and higher miles seem to be getting some attention on the boards. But seems a small percentage. Hopefully one of the usual suspects coil connection, plug torque or injector.
How many miles on car?

It was a blinking light. 98K. Surely it's something to do with torque on the plug since it was just done last week. I unplugged it and plugged it back in and that didn't solve anything. I'm going to take an old coil and plug with me tomorrow just in case.

You might consider swapping coils first and post a pic of the sparky.
If thats not it swap injectors.
Lucky 6 is the easy one!

Wiring fault to ground ? You need to spend time methodically working through the harness looking for damage(rodents?) Suggest you tell us the Fuse by Alph+numeric ,not just amperage so we don't misunderstand.

It was "C2 30A IGNITION, INJECTION, HEATER OXYGEN SENSORS". I put a new one in and it didn't blow. I started the car with cyl 6 unplugged and then cleared the codes after plugging it back in. I thought the fuse would blow again at some point, but it didn't.

How about you get a real degree and understand that not everyone owns the same car for x years. Maybe its too difficult for you to understand Dr....( clearly a joke on your naming credentials) .but I recently purchased the car and not everyone is a so called expert. This is a forum for Porsche owners to assist others, not for comments like yours. Plenty of social media sites that cater to your needs. Join them and let the real professionals chime in.

I agree with Porschetech
I think pissing off people trying to help doesn’t deserve to be treated with respect from the audience
find another website and see how far you get with them
