1999 GMC YUKON DENALI (NOT ACTUAL IMAGE OF VEHICLE)

1999 GMC Yukon Sputtering While Idling

Hello Scotty,

I recently replaced a bad battery in my 1999 GMC YUKON. After replacing the battery the car started sputtering when idling. The car drives fine and seems to have plenty of power when driving. It only loses power when I slow down, and its not in motion. It has NOT lost power completely where it shuts down.

Thanks In Advance,

Emilio

Have you checked the Yukon for a dirty throttle body? Watch Scotty's video: "Make Your Car Run Better with a Little Spray Cleaner" will set you back c. $15 for two cans of cleaner--
