the code p1112 which is the atmospheric pressure sensor circuit range/performance problem. i was having an issue what i thought was a fuel cut. after doing some testing and changing parts out as well as my ECU which i was told ( not going to name the shop ) the problem was still there.my car would hit fuel cut about 4300 RPM but was a little hit or miss but usually did it. i went to yimi sport and had paul take a look at it and let him drive my car and was shocked to feel my car and scared the crap out of him. after him taking a bit of his time to look and ask me a lot of questions and came down to it being RMA dependent he told me it was my crankshaft position sensor. now my car runs like a champ once again and my code has not came back on. big thanks to YIMI sport and both pauls over there. not sure if that is what you other guys might be issuing but that is what solved my problem.
