2003 GMC Sierra Denali Problems

Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Stalling or Low Engine Idle Speed Due to Dirty Throttle Body

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.

Daytime Running Lights are Prone to Burning Out

The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 2000-2003 models is #4114K (trade number).
