Hey man hadn't been on here on my PC in a while. Mine was running very rich, can't remember if that negative or positive fuel trim. I had missed two (2) wires on my harness that went to the o2 sensors. After I hooked them up it started running lean and was missing bad when in closed loop. I believe I need a new o2 sensor. I just have it disconnected for now, runs fine just the check engine light. I haven't had a scanner on it to show the fuel trims. I won't be able to mess with it till about February, as its up at my hunting camp.
If you have any questions just PM me so it shows up on my phone and I'll respond a lot faster lol

Sorry for taking so long to reply. I don't get on this site too often anymore. You should put an on/off switch on the relay so that you don't clog your fan with mud and burn up the brushes.

i have a 93 toyota pickup w/ the 3.0 I recently installed the ford electric fan w the hayden fan control unit. after about 20 mins w/ the high speed wired in it popped the 25 amp fuse going to the fan, i replaced w/ a 30 amp and 2 days later it ended up frying the control unit. I replaced the unit and wired in the low speed it seems to be ok but Im curious if my truck will overheat on long trips or in the summer. The only thing I didnt do was wire in was the a/c over ride but i never used the a/c. any ideas why it popped that fuse and what can i do to fix the problem, because i have a feeling w/o the high speed it will give me temp problems. I havent been back to the mud yet but does anybody think it'll short out or stop working if I get mud or water on the fan.
