Rough idle and power loss in low revs

Hello Team

I seem to be loosing power when Ute is warm in 1st and 2nd gears when revs are low or at idle cold or warm. Top end is not an issue. I’ve done a decarb to the throttle body and cleaned the MAF. I did notice a difference when I played around with the EGR inter cooler valve (I understand this works on vacuum but mine seems to be vary vary stiff almost seized) It throws the standard engine fault code of air system. Could it be the suction control valve? Or possibly a faulty MAF? Or that EGR intercooler valve? Please help me...........

Mine has similar symptoms. I just changed the SCV and it didn't fix it

Probably easiest to get yourself techstream or find someone who has got it or similar.

Try flushing the MAP filter. There's a thread on here to show you how to do it. Helped with my acceleration in low gears.

After mounting a spal fan on the top of the intercooler,connected to a temp.controller ,had no such an issue like before.
