hey fellas i have a problem with som engine code on my stang i need your help on how to fix the problem on the codes the codes are the following
81,82 66,91 and one talking about 02's not switching help please i need to get my car running better thanks
I believe 66 is a MAF signal, which would leave me to believe there is something wrong with your MAF and that is throwing your O2 sensors off. First thing i'd try is cleaning your maf sensor wire. https://www.muscularmustangs.com/maf.php
BTW What kind of problems are you having? Is it stuttering? The reason i ask is because if your MAF is dirty or unplugged it'll make the car chug and stutter like crazy.
