what are the codes. on your year i would assume that your MAF is messed up therefore causing both banks to run rich. its a common ford problem. did you happen to reoil your K&N recently?
i had just a 175 before so i assumed it was a bad sensor since i pulled it and it was caked with white coolant (had pulled the head and dumped coolant on it). but now it's both and im pissed.
i can try to clean the maf, but what else? how can i check the fuel pressure? could it be bad plug? what about an adjustable fuel pressure regulator?
anyone know?! do headswapped GT's usually run rich afterwards? what can i do to check? new plugs? (over 10K miles on copper plugs). adjustable fuel pressure regulator? any ideas? replace the O2's?
sacramento, CA i have no idea what the numbers are right now, but they were high. I failed about a week ago so i took it in and had the o2 sensors looked and they were supposedly broken so i paid for all of that and now i'm thinking it has something to do with maf and possibly old spark plugs maybe??????
