Stalling issues on my 91 Eddie B

What is this silver sensor that plugs into the coil? What is it for?

I've always thought it was a condenser, like back in the old points days. Well, not that old, the Rangers had them.

I actually wonder if you have a partial failure in your coil pack. Have you swapped it out with another just for testing? It may test fine when cold but maybe as it heats up causes a break in the coil and loss of spark? If you can, measure your coil cold and right when it dies on you.

Check this out:

Just for reference, my coil measured as follows:
Front coil pair: 13.17K ohm
Mid Coil Pair: 12.92K ohm
Rear Coil Pair: 13.18K ohm
Each primary winding at 0.6 ohm

I have a new coil, gonna switch it out

I'd bet a few that the silver can is a condenser and is there for radio static prevention.

Problem solved. It was the plug that connects to the coil

How so? Loose? Connectors pulled out? Broken wire?

Had to get an electrician to figure it out

Broken/frayed wire

That's kinda weird that it would only show as a problem when warm though. That would mean 1/3 of your engine wasn't firing, or perhaps the whole thing depending on what wire was bad.

I know, we went wire by wire and practically ripped the truck apart...lol

Well at least your battery cables are rock solid and the wiring where you checked is good Less things to check when the next issue comes along.

I'll be rebuilding the engine in a couple of months. I don't anticipate any more issues with my Ex

This sounds like exactly what my 94 is doing. I have thought all along it was fuel related but now.... not so much. Changed out filter, pump ( only once), FPR. Throws no codes at all KOEO or KOER. Have changed relays and fuses.

It will idle for a half hour no problem. I even drove it the other evening ( when cooler out though) for a half hour running it hard, lots of hard acceleration. Thought I had fixed my problem. Tried to go the landfill transfer and didn't make it two miles on a warm day. ....... I do have a spare but used coil pack I will try next. And see if that changes the problem or fixes it. Thx.

After months and months and even leaving it at a shop for three weeks ( they couldn't replicate the problem) I replaced the Ignition Control Module and have two months of no problems at all. thank God.

The ICM on a '94 ( at least mine) is hidden behind the battery towards the headlight. I think I found the location on here after the worthless repair manuals I have couldn't tell me where it is. I grabbed one out of a parts car and it worked.
