lumpy acceleration
 

can anybody help. car has lumpy accelerartion. i have a mg zt 1.8 turbo. when accelerating from low revs in second and third gear i get 2 lumps/hesitations of acceleration normally about 4 and 5 k. they feel almoust likes bumps or like you are dabbing the throttle quickly. when accelerating from higher revs ie 3k+ i dont get any lumps and the car goes just fine

Sticky wastegate perhaps?

is there any way off telling if its sticking. are there any other turbo owners out there that have had a similar problem. could it be the turbo its self

just been looking on the mg forum. seens like sticky wastegates are a common problem on the 1.8 turbo. good job its under warrenty
