New to the Forum! I have been having this ongoing issue with my truck which throws a P0720 code (and Overdrive Light) and truck also off and on shakes at idle (feel it under front cabin).
I have been to multiple local mechanics who dont know their head from their tail on this car. Looking for dianosis and repair if possible you can refer me to someone. Please advise.
I have swapped batteries, alternators (not OEM Ford), speed sensors and wire, had fuse box repaired, cleaned maf sensor, installed new Idle Air Control, installed 1 new oxygen sensor, cleaned throttle body, installed new fuel filter. Car also gives off a light buzzing sound when radio on and gets louder as accelarating. Any advice?

Light buzzing noise in the radio might be coming from the alternator. Try unhooking alternator and see if the buzz goes away.
