Re: 1996 ford ranger rough idle and misfire

do you have plenty of coolant? it sounds like youre truck is overheating.

~its fine in the morning when its cool
~acts up during the day after being run for 34 miles
~heater doesnt work

those are all symptoms of overheating/low coolant

what I would do is get a timing gun and hook it up to cylinder 1 and see if its getting any power at all if it is, change the plug again. if it still misfires, test the injector.
