my 86 F150 acted odd on a trip. started missing like crazy. was a long
way from home so I limped it for the hour drive(probably not good to
got it home, found mousenest in air cleaner, replaced that and still
would miss on 3 of the 6 cylinders. pulled plugs and found them
covered in carbon. cleaned them up and still no luck. other clue is a
enviromental device attached to the carb plate that has been rusted
away for years is now becliching sooty smoke when it did not before(it
pumped exhaust out but clean).
any clues? I know it is an 86, but i'd like to get it to work well
enough to sell. ran great before this, and got great milage.
I have a feeling there is mouse nest stuff (or mice) in the intake
passages, decreasing the amount of air/fuel getting into the cylinders.
I would pull the air filter housing and look for mouse and mouse parts.
If there's a hole bigger than a dime, they can squeeze through.
Find someone with a borescope and take a look, you may have to
partially take apart the intake to get close enough.
Or get a shop vacuum and rig a chunk of small vinyl hose, and one of
those flexible cable grabber tools, and go probing.

no nest material inside the filter, just on the outside in the air
cleaner, so I am assuming none go into the intakes. i'll give it
another glance, but i am sure it isn't the issue.
I am thinking that maybe the cat got plugged when running overly rich
because of the nest stuff plugging the filter, anyone with
suggestions? possible that might be BS too because i dont know if the
exhaust is still attached that far (it IS an 86)
