I have a 2003 996 c2
All day yesterday she was fine, driving up and down hills here in Germany.
Then last night on my way back, a CEL was on
The idle then dropped down to low 300's and then would come back up
The battery power dropped, oil pressure and idle dropped at the same time
I am leaving her parked today, I have to work all day and tomorrow I will take her down to the shop
Anyone have any ideas, I turned her on today, and its cold. The idle was fine, but she immediately threw the CEL at start up, and its constant.
I have a Fabspeed Intake, and I did have muffler deletes, but I put the OEMs back on.


So I was able to get the codes.

So misfires in bank2, and the cam position sensor is over retarded...Im guessing of course.
Should I start my car again? or flat bed it now?
smoke comes out of bank 2 tailpipes. The indy said it was probably coil packs or plugs. I just changed the plugs, and the packs look alright. But would that cause the cam position to throw a CEL?
