Hey guys i'd like somehelp on figuring out how to lean out my car a little bit. It is running super rich the exhaust has an enourmous amount of sut on it. I thought that maybe one of the o2 sensors was not hooked up but i checked and they both were (obd-0). What could be causing me to run super rich and what could i do to fix it.

 

what ecu are you using?

also do you have a fuel pressure regualtor?

 

switch the o2 sensors and see if that help. switch them as in switch the wires going to each. i think they are probably backwards

Do you know for sure which o2 sensor goes to which ecu pin?

I am running a pr3 mugen chipped ecu and do not have an fpr

 

i dont think you can switch them up at the sensor becuase the plugs are different
