What RPM does this judder appear at? If its while accelerating it could also be because of a dirty fuel filter or fuel pump.

Yup I read the DFCO and also thought it could be because of that. The cut off when you back off the throttle is very sharp which jerks the car.

Also when you back off then again accelerate there is a jerk especially when you do it really fast in stop go traffic.

The jerk when the cutoff appears is a forward jerk so it could be because the fuel is getting injected after cutoff.

So what's the difference between DFCO and IAC valve. their functions seems similar.
