I have an '85 E-150 with a 351 engine, and a problematical ignition module. The used vehicle came with a Wells replacement unit when I purchased it, which later became intermittent, so I replaced it with a Borg Warner, that just up and died just 6 weeks later.
What, if anything, can I put in there that is likely to keep working long-term? Are genuine FORD units any better, or are they just more "Fix Or Replace daily" devices? Is there some sort of high-performance device available? This is worse than having one of the old mechanical distributors! At least they would work for years, and if they stopped working, they could usually be put back into action without having to wait for oddball electronic parts to be shipped from Timbuktu.
My ignition module is a bit bigger than a pack of cigarettes, seems to be potted in some sort of soft black plastic stuff, has a blue connector, and is mounted up forward, where it doesn't get particularly hot. Further, the intermittent unit does NOT seem to be temperature dependent, as it is just as bad when cold as it is when hot. Hence, while this make/model/year is on the TFI lawsuit list, it doesn't seem to be having the TFI heat-related problems.
Thanks in advance for any thoughts you might have?
Steve
