ok..high idle problem gone...
220 miles maybe more with OBD on and no misfire code. i FEEL a light tumble in motor when im at a stop in drive. stayed in driveway in drive and fell it every 3-4 minutes,sometimes couple min longer.... i feel it,lol. anyway,at about 70 mph which it does every day i feel it too. its feels like a tumble/stumble...slightly.
when truck had vacum leak and was at a high idle at a stop in drive i felt misfire once cause i felt moter tumble ....which i think "boom" code came up....but since idle fix,idle good.. its ok, no code but stumble is still there.
....thinking change BOTH coil packs....and then the plug number 3..cylinder 3 cause that was code. or change plug first. plugs and coils,wires,everything motorcraft but the MSD coils...lets say 12000 miles since new but like 3 yrs. ago or more. low miles for time span.
