I have installed a 1990 ford 5lt 302 EFI engine in a 1941 ford with a C-4 Automatic and used a Ron Morris after market wiring harness for the ECI. The engine has been completely rebuilt and all of the sensors including the O2 sensors have been replaced. A re-manufactured ECI installed. The KOEO test has a 11 pass code, the KOER test throws 42, 92, & 75 trouble codes. Because there are no provisions for a Brake On/Off circuit, code 75, could that causing the 42 & 92 codes? And if not where should I look next. I have replaced all vacuum hoses. I also replaced the fuel pressure regulator. It has 18 inches of vacuum at idle, 165 lb. Compression on all cylinders, 40 psi static fuel pressure and 30psi running.
I can smell the rich exhaust and it is driving me nuts trying to figure out what can be causing the rich condition.
have the same problem?
