05 Kia Sportage engine jurdering EGR light on

[Sportage123]

05 Shortage car jurdering at 1600 revs in low gears, EGR code coming up, new EGR valve fitted, code back up again, new accelator fitted, car still jurdering, vacuum type system on egr.
Seen this type of problem on other forms tricky one.

Kia Sportage 05 , 2L Diesel , keep getting P0401 Egr code on dash.

Replaced Egr valve for new.
Replaced accelerator pedal.
Injectors removed cleaned and tested.

Second issue, Jeep engine is juddering in low gears at around 1600 rpm.

Other Kia owners have reported this to main dealer and the fault reappears.

Anyone else have this problem??
Thanks

Replaced the Egr value.
Didn't go near the actuator.
Engine check Light back on.

Will have a look at the actuator

Checked Egr solenoid opening and closing ,
working ok.

Checked Egr valve opening and closing ok.

Will see does the engine code P0401 come back on.

Regarding the engine jurdering intermittently at 1600 res in low gears this could be another issue.
