I have a 2017 991.2. Recently had a check engine light. Code read as misfire cal.#1. Shut off car, locked it. Next day CEL is gone. Checked with my iCarsoft, showed misfire. Cleared the code, car was fine for about 25 miles, and the CEL returns, but car drives fine, like before. Then 30 sec later, noticeable misfire, basically 1 cylinder dead. Hook up iCarSoft. OBD2 shows cal #1 misfire. But when I run the diagnostic under Porsche, I get code not in library.
3 codes
P00ec8e
P00eb22
P00ed5a
I have tried multiple times and this is all i get.
Any help or ideas what I am doing wrong.
Thanks,
Dave

Best guess....
If you eliminate the ec, eb, & ed parts P0022 & P0008 are ECU camshaft sensor errors that might prevent a cylinder from firing.

Maybe I will see if I can erase those faulty codes, and rescan and see if the proper codes do come up.
