Im getting codes out of my 93 truck 5.8L ZF 5 Speed 4x4.. Did mass air conversion..... codes are KOEO 67 81 82 84 67.... Continuouse Codes 31 66 96... I have my boock that tells me the codes but not sure what some mean...67 clucth switch failure, My fluid was low and every once in a while my pedal sticks to the flow so I bled the system and it works fine for a week or so and then I have to do it again...slow leak in bell housing...81/82, Air management 1 and 2 circuit failure... I have no clue what that means.... PFE,EVP or EVR ciruit below minimum voltage, Not a clue....MAF sensor input below minimum voltage. I know what it means but I dont no how to fix it, thought the computer took care of input votage...96 Fuel pump seconday circuit failure < EM DASH > battery to PCM... Not sure iether What and where is pcm... So I have been able to track down some things however Im not the ford geniuse ! Any help would be great

 

Did you move the pins to the correct locations for the mustang computer? The air managment codes are for the TAD and TAB solenoids (pin locations are different than the truck). The clutch switch is different on the trucks, I wouldn't worry about it just yet. Test the MAF output to see what the voltage is at idle, it should be around .6-.8V. The code was for an intermittent low voltage, so it doesn't sound like it is not working all the time. I wouldn't worry about 96 just yet either as long as your fuel pump is still working. 31 is the EGR not opening, probably due to code 84, EVR solenoid not there.

 

OK I will look at the MAF then work my way down the list... thanks for the advice
