    Just had a new cat fitted and got my car back literally 10minutes ago, but now when i rev it from idle it like misses a fire and doesnt rev up straight away?
    Anyone got an idea?
    Thankyou

    Does the cat/exhaust blow? Where the lambda's plugged back in the right way? green in the top blue in the bottom?
    If not get plugs swapped over, chances are the cat could be fucked already if this is the case
