Over the last few days, and after a recent oil change my 2001, RWD, 3.0L, 5 speed manual Ford ranger has started jerking/bucking when accelerating. It happens in every gear whenever I go past 1/3 maybe 1/2 throttle. No evidence of clutch slipping, no loss of power, no engine lights on, smooth idle... It almost feels like its not getting fuel in a pulse pattern

Any ideas oppos?
