I have a 2000 OBW, 2.5L-5MT, approx. 180k km. Recently it's been exhibiting some wierd jerking and hesitation behaviour. It seems to occur mainly under slow acceleration or cruise control mode. If I'm slowing down, a slow steady release of the throttle would at some point produce a hesitating jerk. When accelerating, if I'm accelerating slowly, it would also jerk. If I'm giving it some heavy gas, then there would be no problem.
It also happens while in cruise mode. It seems that slight changes in throttle position create disproportionately large acceleration or deceleration. What could be the cause of this, throttle position sensor, fuel, spark, etc.?
