Hi everyone,

I have SES code P2A03. I have done some research and possible outcomes are:

dirty MAF/MAF is bad
Exhaust Leak
O2 Sensors

the only modification is my exhaust : Top speed Pro1. But, I have put the exhaust on the car well over a year ago and just got the code about a week ago.

I guess first step would be to clean the MAFs but has anyone had this code with a different issue that I have not mentioned?
