    So I thought I'd check my readiness using vcds and everything passes except catalic converter,I have tried passing manually but can't get block 034 in basic settings too initiate??? The value was 1.78 but hadn't passed the test all other tests passed but this one?


    Pre cat sensor is a couple of months old tops!

    Getting some /white/grey smoke on startup untill warm short term fuel trim after reset was 2.1 which indicates a vac leak?? Ltft was still 0?,when on full throttle I have been told I'm chucking a tad of black smoke out?? Turbine blades on exshaust side were black with soot when I had down pipe off my previous turbo was white inside running nice??could I be overfueling on idle??? going too double check carbon canister pipe work today as some have reported rubbing on washer bottle?
