If your intake system is dirty you may notice that your vehicle is running rough, hesitating or even stalling. This is caused by carbon build up limiting the required amount of air flow and fuel needed to fully ignite the cylinder. When the EGR system is dirty you may notice such symptoms as reduction in power and acceleration, a rough idle and decreased fuel efficiency. We highly recommend cleaning the system every 40,000 miles as preventative maintenace instead of waiting until the vehicle is experiencing problems.
