Thread: 3.0 hesitation at low revs

Hesitation at around 1300 rpm that needed significant throttle to overcome in on/off throttle driving in manual mode through the winding climbs into and out of Kangaroo Valley yesterday afternoon probably wasn't caused by the suspected MAP sensor because the sensor looked clean this morning. Sticky primary turbo vanes or actuator could be the culprit but as the primary turbo is always getting a work-out I suspect the cause is something else.

Has anyone experienced such hesitation especially in a 3.0 and if so, what was the cure?

Thanks Ken. This only occurred under load whereby progressively squeezing the pedal caused the engine to progressively produce less torque until it almost died then jumped to life when the pedal was given a good push. I was allowing the revs to get quite low coming out of the hair-pins then running up the revs before dropping right back for the next bend, sometimes bumping up a gear in between before dropping back again.

I replaced the MAP sensor with a new spare and cleaned the other so will see if the hesitation re-occurs, although its not often I encounter those particular circumstances.
