Car hasn't really been used in the last year due to getting a new job with long commute but it needed a new clutch so last month i fitted a new clutch.

After fitting the clutch the car seems to have generated a misfire on boost, The AFR goes **** and the boost gauge splutters.

I have replaced the intercooler Y boost pipe as i knew that it had a slight crack in it under jubilee clip on the join to the turbo and also i replaced the boost control solenoid vacuum pipe as that was also splitting at the join to the actuator t-piece.

Air flow sensor was replaced about a month before i stopped using the car so i am hoping that hasn't gone while its bin sitting around.

I have done an ECU reset after the above as well and the misfire is still there.

Does anyone have any ideas of where to explore next?

Car worked spot on before i changed the clutch i have checked everything and i am 99.9% I've not missed a wire connection of vacuum connection.

Any help would be really appreciated otherwise i am going to have to take it into a specialist.

Thanks

sounds like a hose to me somewhere
runs OK off boost?

Heple

No not really, splutters sometimes off boost and idle sometimes dips. i've checked the boost hoses they're 100% ok. The vacuum hoses i'm 99% sure are ok?

Could a dodgy Lambda cause it?

I do apologise 99green (probably getting tiring now ), but it does make me laugh. It's that whole "I know! I know!"-based enthusiasm in the advice that gets me every time, etc... (I'm far too easily pleased when it comes to anything like that ).
