I decided to have some fun with an Audi A7 a few nights ago on the highway and I hit speed cut at 120mph. I let off and maintained a speed of 115ish till the A7 backed off. when I exited my car started running funny. Pulled over and looked under the hood nothing was wrong visually. Managed to get home and I pulled one code out of the ECU. DTC 31 map/maf sensor open or short. At idle the car runs stupid rich, 10.0-10.3 AFR, drives okay if I lightly hit the gas, hesitates when I go hard on the gas. New plus installed, coils are new. I am thinking about throwing a MAP at it but would like to know if somebody has had this problem, ant inputs would be very appreciated. Thanks
