That is a set of odd symptoms. (demon like) (i guess hot engine only)
bucking is mostly spark.
but why and which part?
spark wires ok?
with the DIag jumper planted, and 12s going, drive it. get it to buck see if 12s just beats out, no drop in cadence of 12s, and no new codes pop up then clear.
by cadence mean, 12,12,12,12,12s no change'
not 12,12,12,41,42,12, 12......
or 12s die for a time? goes dead, no flashing codes at BUCKING? (implying power loss, even loose fuses FI, or IG coil)
bad grounds? in the engine bay. engine block grounds? ,distributor base grounds wires at bolt mounts?
spark coil going bad slowly.
id do spark plugs, wires ,cap rotor and cross fingers. if no good now, COIL. spark igniton coil on fire wall.
fuel loss, is usually smooth not bucking violent.
hope you find it easy, cheers and have great Sunday.
