A Loose or worn gas cap may cause Check Engine Light to illuminate.

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.

The front and rear light bulbs are prone to premature failure. Our technicians tell us that the front bulbs can be very difficult to replace.

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.
