The same piece of sh!t, with the same problems I'm having mate!
I cleaned the throttle body and put a new air filter in, and that has helped alot! It still cuts out, but only very occasionally. Clean or replace the stepper motor (ICV) as a first step, but these are known to blow ECU's when coil packs spike. I reckon this is whats wrong with mine, but I only paid £150 with 8 months tax and 7 Months MOT with 82k so I couldnt give a toss about it tbh!

Also they are known for injector and FPR failures which could cause issues with over/underfuelling too.
