1995 mustang obd 1 codes 181 and 189 codes
My car is a 95 GT with about 186k on it. Check engine light has been coming on. It sometimes comes on at light throttle at about 3k rpm and then goes out after shifting. I finally got a code reader. The OBD 1 codes 181 and 189 came up in the scan. The KOER tests all pass. I know these codes mean that the computer has reached the control limit on enrichining the mixture and reports that the system is lean (both banks). Don't want to just start replacing parts. I am guessing that its possible the MAF sensor since otherwise the engine runs good. Anyone have this same problem and what did you to fix it?
