i am having a problem with my golf. the revs get stuck at 2.5k revs and the power suddenly drops but then comes back on after a few seconds. it happens all the time in every gear. the car doesnt go into limp mode and it doesnt show any lights on the dashboard. the dpf and egr have been removed and this problem is still occuring. i have also had my cat removed. please any suggestions will help. i have tried taking the car to mechanics but they seem to not know the issue. i disconnected the MAF sensor to see if it would make a difference but it is still the same.
