Aaarrrggghhh
 

Decided to drive my Box to work for the first time since I got it back from the body shop. Started fine, ran fine for 17 miles. Low on gas, I decided to pull into a gas station. Just as I started to turn, my CEL started flashing. Oh crap I said. Pulled in, turned it off and scanned it.

A number of codes later:
P0300-P0306
**** P0336 & P0341
P1313-P1318

Where do I start???
Will changing the CPS resolve these problems?
Suggestions on the Catalytic converter issues, I'm in a no smog state. Can I bypass them?

PLEASE HELP!!!

How low on gas? Have you started it back up since filling it?

A bad Crankshaft position sensor will cause the misfires, so I'd deal with that first.

CPS: My first thought was a bad connection or rodent chewed wire, but if it ran well for the first part of the drive, I'm thinking it stopped working well once it reached a certain temperature. I had a similar problem on a Cayenne and before that a MB ML-430. Check the connection and wires, then replace IMO.

After cooling down does it run okay at first? Does the problem come back after it's warm?

Your "telltale" codes are the P0336 & 0341; the first is for the crank position sensor, the second is a cam position sensor. Most likely, the second code was triggered by the first, as was your misfires.

The gas idiot light came on just before I got to the gas station. The flashing CEL came on as I was turning into the gas station. Tried to start it while at the pump and it tried to fire but didn't. Didn't want to press my luck and had the car towed home.
Will I cause harm by trying to start it?

If it's the CPS, then no, no damage will be done trying to start. It may start when cold but fail when hot. This is a common-ish symptom. Pretty easy to replace it from the pass side wheel well.

There are replacements that fit and are not having the Porsche tax added. Do a search!

Thanks to all that replied. I feel better. Only need to have one Porsche project going on at a time. My 66 912 is going to occupy my time and wallet for a while...
