   similar to mine, i removed the throttle body, gave it a MEGA clean and changed the lambda sensor and it was fine.

    Think mine is the inlet manifold leaking bad, we sprayed brke cleaner around the seal when it was running and it sucked it straight in.

    To check for air leaks, remove the filter piping, so you got access to the throttle body, start the car and cover/seal the hole throttle body with your hand. It should die after a few seconds, if it doesn't, means you got an air leak somewere.

    It depends how much of a leak its got as if its small it wont effect it at all. We put all breathers and pipes on and srayed brake cleaner on the inlet joins and it sucked it straight in.

    yeah but you'd hear the leak more, no matter how small or big it was.
