codes 33 & 36
My 1989 formula 350 started running rich one day so i bought a scanner from autozone and got codes 33 & 36. One is for the maf burn off and the other is a maf high freq. I have replaced the maf, maf relay and the maf burn off relay and it is still running righ and when i say rich i mean that i cant hardly stand to ride with my windows down. Any ideas?

O2 sensor. It can be weak on voltage output, which will cause the ECM to richen the mixture, without setting a trouble code.
