i cant find the damn list of pcm codes for 93's. it used to be on the speed density forum. anyone got a link?

 

code 45: Rich exhaust. Check the evaporative charcoal canister and its components for the presence of fuel. Check for fuel contaminated oil. check the fuel pressure regulator. Check for a leaking fuel injector. Check for a sticking egr valve. Replace the oxygen sensor.


All this was taken from my Haynes manual. Good luck!

 

thanks (dammit!)

 

Did you ever find out what the problem was with the code 45????

 

it turned out to be a bad plug wire
