I did the turn key thing with my 97 4.0 and got these codes: 12 43 42 55 (In that order). I had them for quite a long time, and the same ones return after resetting the computer. I did a stroker, and they didnt show up at first but now the exact same codes are back. I looked them up in my haynes manual and found out:
12- Alternator light stays on. I dont know how exactly to fix this, I dont have any charging problems.
42 - Noisy in one particular gear. Havent noticed anything, even changed transmissions for different reason and still got the code.
43 - Slips out of gear. No, hasnt happened. Again I had the same code before I replaced the old trans, and after the new one was in. New throwout, pilot bearing, clutch, no "slipping out of gear."
55- Vibration. A lot of stuff has been changed in regards to what haynes says. Trans, rear axle, engine, rear driveshaft. Nothing in pursuit to fix this code, just stuff along the way.
I cant seem to get these particular codes to go away. Every once and a while Ill get a 21, that it is dieseling. It isnt, and never has. Is it just my computer being retarded, or are these actually problems Ive yet to fix even when replacing parts?
