Done to death I know, but I have searched every where on all forums and still come up blank with my car. It hunts at 2500-3000 revs, common problem I know on the td5 but so far its had...
Injector harness
engine loom
new standard turbo hoses
waste gate vavle is free
waste gate solinoid valve replaced
new air flow
egr bypass
fuel press reg
no faults codes showing
last week i thought i had cracked this problem, i discovered the turbo pipe on the egr valve bypass kit had slipped down the casting so narrowing the diam of the pipe and eventually closing it under load, it was fine for a week or so but now the problem is back, stipped it all out today checked all turbo hoses i can't see anything that could be causing this now can anyone see anything I might have missed?
