So, 5.0L from a 1990' TownCar, with AOD into my 86' B2.
Mounted, fluids buttoned up. Wiring spliced to Bronco, Plug in the EEC and hit the key. VROOOM.
Very exciting.
BUT it starts alright and runs, good enough to drive it 10 min into town for exhaust. It did not want to run well enough to drive home from exhaust. I re-set the EEC, then was able to drive home. I was NOT happy with how it was running.
Started investigating. Pull 1 spark plug wire off the distributor and see what changed. When I pulled 7 of the 8 wires it made a dramatic/noticeable difference. The #4 cylinder nothing changed, it was still getting spark, but having that plug wire disconnected did not change how it was running (which was poor to begin with) (BTW all spark plugs where gross with soot, I think it was over fueling due to #4 not firing and just cycling oxygen onto the O2 sensor)
So, we have spark to #4, obviously time to investigate fuel. Pulled injectors, sure enough #4 was gummed right up. Pulled and cleaned all injectors. Re-O-ringed and re-installed injectors (vegetable oil on the O-rings). Reassembled intake and all that junk. Turned the key. VROOOM
Very exciting.
It ran way smoother and sounded much nicer. For about 5 minutes.
Then it began to get worse and worse, back to the point of running like a bucket of garbage, like it was before all the injector work.
SOOOOO obviously the computer is getting problematic information from somewhere! Everytime I re-set the computer it runs awesome, for about 5 minutes, then continues to get worse. These comps fun of averages (right?) so it is getting a signal to do something different, which is making things worse.
ANYBODY GOT ANY IDEAS WHAT MIGHT BE GIVING ME THIS BAD INPUT?
PS: all the emissions trinkets on the passenger side of the engine are gone. A: no space for them B: why would I want that junk?
Could it be that this emissions junk sent the comp some sort of signal that is now absent that is now screwing me?
