I need some help here I have a p1132 and a p1152 codes both for bank1 and 2 rich. I can not figure out what my issue is . I have an 03 4.6 sohc 2v with a Procharger. My fuel setup is 42lb injectors, and cobra dual pumps and tank. My maf is Pmas maf calibrated for 42s. It's been tuned for almost two years now and I havnt changed a thing. I checked all my vacuum lines they were all good even my gauge was reading good. Fuel pressure koeo was around 40 running at idle around 30psi. The a/f at idle is reading 11to12.5. The 02 sensors at idle for the upstream are both in 900s not realy switching to much. I replaced the frps and still te same issue checked the iac looked at maf n it didn't look dirty and it's a blow thru setup. Does anyone have any clue I drove the car down to mustang week (10hrs) no problem and when I drove home about 5hrs in it three these codes and started bucking over 1/4th throttle. I'm stumped if anyone has any suggestions please say something I'm stuck over here!!!!
