A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.

When my 2002 GMC Yukon Denali initially starts up, it is a very low idle. Sometimes, but not always, it will stall. It starts right up again but the fcqt that it stalls is very troublesome
