Some advise needed

[japjim]

Just recently but not all the time, when giving my rex some stick in 3rd and 4th gears at around 5-7 rpm it seems to jerk.

any ideas what this could be any help would be much appreciated.

anyone anything?

do you see the red light on the dash flash up ?  It could be det, or fuel cut.

Nope no red dash light, have not seen that flash since i have had the ecu mapped.

Even though i am getting some high knock readings even when driving off boost at around 30-40mph but guessing that could be a faulty sensor.

Did just a general check of the engine bay from what i could see everything looked normal but oil was quite low and also quite low on petrol, when i remember the jerking happening.

plugs might need changing ?

Is it when you are going round a bend ?  You can get fuel cut because there is no swirl pot
