GMC Yukon XL 1500 Stalling or Low Engine Idle Speed Due to Dirty Throttle Body

(9 reports)

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.

Solved by Throttle Body Cleaning. Watched youtube video on throttle body cleaning for 2003 Silverado. Took me 10 minutes and most of all, it acutally worked! -
