Hello guys, I have a 90 series D4D 4 speed automatic. When I travel above 40mph and I release the acceleration, the rpm drops to idle speed, when I reapply the throttle, the rpm jumps back. At that moment, when I apply throttle and the rpm jumps back, I get a big hit, like something is loose down under...
Some bushings were replaced in the back, the situation is better, but still present...
At 60mph when I enable the cruise control, I get a so big hit, when the engine starts pulling that a sleeping person would rouse from sleep.
Do you have any tip what to look for, what could be wrong?
