    no harm to clean out the throttle body, if that does not resolve it then i would look at the other most common culprits, pre-cat lambda, airflow meter, coilpack.

    I have the same problem I'm assuming throttle body too it only happened since I put an air filter on it though.

    if the air filter is an open cone induction type kit then, yes this may well give you problems as the hot underbonnet air they draw in upsets the air flow meter
