Unhappy

Hi Guys
Well i bought that rebuilt 96 318i. So far so good. Handles well, and is pretty quick. One issue that I noticed that was not there during the test drive: while sitting at idle just after coming to a stop, the motor surges from about 900rpm to 1300 , and back. It does this almost every time i come to a stop, then it stops after maybe 10 surges. The surges are quick almost as if I was blipping the throttle. Happens cold and op temp.
Any ideas?

Manual.
Happens in neutral, and in gear with clutch depressed.

Well after reading some other boards I fixed the problem today.
I took aprt the throttle body, and cleaned it, and also cleaned all the contacts on the two electrical connections on the throttle body.
Then I adjusted the idle.
She is happy as a clam now, no more surging idles nicely at about 800 rpm.
