Done any work on the car recently? Any other symptoms?

Note the search capability of the forum and enter the codes as few questions about a 10 year old car are new and there is liable to be a prior posting and answers on the subject.

Good luck.

Yes I changed the oil, and I put an aftermaker air filter, and disconected the negative cable of the battery to reset the computer. The same two codes comeback again.

I place an original porsche air filter but the same codes appear again. Also I replace the oil filler cap (o ring type) but the same two codes appear again. I drove the car con the service engine lights on, but now the condition is worst: A lot of smoke from the mufler and the car RPM is fluctuating. In addition I cleaned the airmass sensor but not different results.

Do you have any idea what could cause the problem.

Do you know what is bank 1 or bank 2.

1128 and 1130 are the same problem on opposite banks (1128 is on cyl 1-3; 1130 is on cyl. 4-6). Most common cause: Leaking air intake............

Bank side

Here.

Suspect AOS...look at condition of throttle body or pipe just outboard of it to see if oil is being sucked into the intake. If there is heavy oil, you probebly have a ripped AOS. Replace the separator, bellows and the hose. Here

Or, when doing work on the air filter, did you somehow create an air leak?
