You have a faulty throttle body, get the idle circuit\system tested or live with the issue!

Vacuum leak ?

I have this same issue on my car but to compound my misery, the engine runs on for a little while (max 30 seconds) after I've taken the key out of the ignition. Safe to assume it's the throttle body also?

Anybody know the part number so I can fish around on ebay?
