Deposit Buildup on Throttle Body May Cause Low Engine Idle on Chevrolet Suburban 2500

The engine idle may be lower than normal due to deposits built up on the throttle body, which can restrict air flow at idle. To low of an engine idle can result in a stalling condition. Performing a throttle body service will generally correct this concern.
