2006 Cadillac Escalade EXT Problems

Check Engine Light Due to Restricted Secondary Air Injection Check Valves

One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.

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.

Popping Noise From Muffler Heat Shield

The muffler heat shield may become loose on the muffler causing a rattle or popping noise. Our technicians tell us there is a kit available from GM to correct this problem.
