Rough idol after engine cleaning - SOLVED!
Okay so I cleaned the engine and running rough ever since...
I have checked the d-cap dry as a bone, changed all the plugs and wires, and then tried running Seafoam into the carb to see if water got in somehow... That made it run pretty smooth for a few little while last night but this morning it was back to being crap-tastic...
Any other suggestions? I don't see how but maybe a vac line came loose? I checked everything I could see last night. This is my first Ford and it's as old as I am! My main carb experience is from jeeps so this 302 is taking some getting use to...

I usually spray some Contact cleaner or Starting fluid into the distributor (make sure to let it dry out thoroughly), if it won't start after an engine cleaning. I also use Di-electric grease in all of the electrical connections regularly. That would also include the spark-plug wires (both ends).

Spark plugs and wires, vacuum lines, electrical connections and components etc... Unplug or inspect for water etc..
Did you run the seafoam in the fuel? If so change the fuel filter. Water in the oil? Change the oil, etc...

Checked the oil it was fine, sea foam was into the carb directly so filter should be fine, but I may replace it anyway. For $4 why not while I'm working.
I am really beginning to think it might be electrical though. The vac lines seem solid when I've looked in the past, what could cause that?

Pull the distributor cap and check it and the rotor area for wetness. WD40 will cure any you find. Vacuum diagram should be on the label at radiator support. If yours has 'gone', look in my albums for the Vac hose routing diagram.

Nope... I really think it's electrical (as in something is wet/has water in it). I had a Cj-7 that would do something similar and ended up finding out it was a resistor or something (can't remember what) that was filling with water when it rained. Inverted it and all was fine...
This is so odd to me that it would linger for 4 days now.

Went over the vac lines checked in detail and I am stumped. Bought a fuel filter but didn't get it changed as I was coerced into drinking lots of beer and watching FSU create a train wreck last night... Paying for that one today (getting too old for this stuff).
So I am going to change the distributor, oil/filter and the fuel filter today. I am running out of options that I can think of at this point.
Haven't tried a compressions test (don't have a meter) and I'm still waiting to do the above. Taking it out to my Dad's where we can do some more...

have you pulled all of your sensors in the engine room and check for moisture? my guess is you have moisture under one or more of those...do you have compressed air and a blow gun? or, maybe the budget officer's hair dryer on full blast????? be sure to wipe off all fingerprints and any lingering dna off the dryer and replace EXACTLY as you found it
