Engine codes
Hey guys finally found my ob2 port all tangled up in the wiring under my stearing wheel and when i went to autozone to get the free ob2 reading 8 codes came up
they are P1250 P1188 P1189 P0101 twice P0430 P0173 P0420 I looked in the 101 projects and none of the codes match I do not have a cat -- staight pipes which was the guy before me who did this mess to the car -- so im guessing some of those r o2 sensors and by the way the cars running when it starts up im guess at least 2 injectors please let me know what these are if you know or maybe a site that would help  thanks( ps its a 97 m3 coupe stick)

An internet search should tell you what each code is. You will probably get more help is you list the codes and the description of each code.

thanks for the advice
went to check what codes were left when i went back to get another obd2 test and the only one left is P0101 which says MAF or VAF which comes up twice ill type it into the search engin but I'm not sure how much thats going to tell me -- if you guys know what commonly goes wrong with the intake or mass air flow let me know |

No other codes came back even though you are not running O2 sensors? The previous owner must have bypassed them.
I cant think of anything the MAF code could mean besides a bad MAF. How well does it run with the MAF disconnected?

when i disconected the MAF it ran the same maybe slightly better, does that mean that the MAF is dead and it needs to be replaced? and the o2 sensors were configured into the micky mouse weld straight pipes the guy instaled before me -- since i cleared those codes with the obd2 reader those o2 codes havent come back and ive driven it for about 300 miles so im not sure thats an issue although if it does become an issue ill probably just by pass it
