idle issues and other fun questions.....
1980 f250 4x4 (300 I6) was running great..........
halfway though a long roadtrip it started idling a bit high (around 1200-1400). then it wouldn't idle at all. without giving it gas it just dies. not sure if it's related but at or around the same time my oil pressure and water temp gauges both dropped down a bit. the oil gauge was always at the same spot more or less, and now it's a bit lower. also, the temp gauge which was always at or around the same spot (would move a bit up and down depending on driving conditions) is now just at or below the area on the gauge that indicates normal. when the engine is off both gauges move all the way down so they're def moving.
truck starts fine, runs fine, no appreciable loss in power or any other difference while driving, just won't idle.
there's plenty of oil, plenty of water in radiator, there doesn't seem to be any oil in water or vice versa, no smoke or anything bad coming out the tailpipe.
I don't really know much about this motor and the truck is new to me so any and all help or suggestions would be most appreicated.
fwiw, the entire carb/air cleaner seems somewhat loose, as in it's not totally bolted down to the top of the motor. not sure if that's normal or not, but it seems to have a good bit of play.
thanks in advance
