I have a 2002 Hyundai Santa Fe. When I stop at a stop light or am sitting in my driveway with my car in drive and my foot on the brake the car bucks every ten to fifteen seconds. Any idea what this is?
This may be an issue concerning the IAC (idle air control)system, also an idle surge can be a vacuum leak as well, I would start with a scan for any fault codes and get the AIC and throttle body cleaned, start here.

It could also be due to the engine misfiring intermittently. Get a scan to check for trouble codes if the MIL is indicating.
