My car has started to act up once again, after running good for a long time. Im throwing a P0172 too rich code and a P1132 code. My question is how to i fix my car, have already tried cleaning the MAF, im at a lost as to what to do. Any insight will be appreciative and helpful thanks.
FYI my car has 145K miles, long tube header and intake.

 

Do you have MILS on the rears or have them turned off via a tune?
