The rear Oxygen sensors are a critical element in fuel control (unlike other vehicles) and can cause an emissions test failure for high CO and HCs. The sensing element cracks and and reports an erroneous steady state lean condition which confuses the computer, which in turn makes the fuel mixture overly rich.
The idle air control motors tend to become carboned up at around 100,000 miles and will cause a start and stall and/or stalling at stop sign problems. Our technicians tell us that many times these valves can be cleaned, however, the sure bet is to replace the idle air control motor and clean the throttle body.
It is important to regularly check the valve clearance as the exhaust valves may become too tight. This will lead to valve failures, which are expensive to repair.
It is very important that the rear level sensor is properly bled after any brake work or the rear brake stopping efficiency may be compromised. The Front Brake Rotors can wear causing a pulsation felt in the brake pedal.
