So a few years ago when I wrecked the Wrongco.. I got a new front clip from what I believe was a 96' F250 or F350 with a 460 and ZF-5 manual trans.

On the fender when I got it was the ignition module.

The numbers on it are F1SF-12A297-C1A and below that is 4L05A.

I just want to check, but I'm pretty sure that I already know the answer. The module won't work for 96' 351w correct? I had it on the truck when I first got it running again, but it ran really, really rich.

 

You have the correct black Ignition Control Module. Many parts manuals are wrong, including Ford. 1994 and up trucks use the black colored CCD-style ICM.

 

So will that work with my 96' 351W and E4OD?

 

Probably. The black Motorcraft are hard to find. I am running a Taurus 6cyl in my 5.8 and my spare is from a straight six truck 300. Both work great.

The wiring connector and heat sink are the same but the computer controls the dwell and the wiring is different in the later year CCD design.

I bought a couple of Motorcraft grey ones which do not work so let me know if anyone wants them.

Of course pulling codes is the first step for running rich. Thermostat should be 195. Then if codes are good, look at O2, ECT and ACT.

 

My current codes are p0171 bank one running rich. P1506 IAC over speed. P1401 EGR sensor messed up (but I've know about that.

 

Yes, the black ICM from the other truck will work just fine.

p0171 is bank one lean not rich, isnt it? combined with p1506 idle speed, i would be looking for a vacuum leak on the pass side of the engine.

 

Well I drove the truck today and it idled correctly and seemed to run better then it has been in the last week. I haven't narrowed down a vacuum leak yet but as far as I can tell I don't have one.
