I have a 2006 997 C4S that has the following CEL codes P1043,P0300,P0301,P0301,P303,P305,P0306,and P0304 can any help me with the issues i might have?


Welcome to RennTech :welcome:  


P1043 Electric air cleaner flap
Possible fault causes
- Short circuit to B+/ground or open circuit in the control line
- Open circuit of power supply to air cleaner flap solenoid valve
- Air cleaner flap solenoid valve faulty
- DME control module faulty
These look like a problem with the air cleaner/intake flap.
All the rest are cylinder misfire codes.  I would address the flap issue, clear the codes and see if any of the misfires return.

Thanks for the feed back,  engine light cleared on  second day of issue,and hasn't come back. Believe it could have been a fuel issue but reset codes and will monitor. That one P1043 needs to be addressed thanks for input.
