Idle performance and EVAP Purge Valve

Erratic idle performance of the engine is often attributed to quality of ignition components, Idle Control Valve, AFM sensor, Throttle Position Sensor, etc. A part of fuel injection system that is often ignored is Evaporative Purge System, cosisting of a canister that collects gas fumes from the gas tank, and a valve that directs the fumes into the engine. The valve is subject to blockage by charcoal from the canister, which results in fixation of the valve in "open" mode responsible for introduction of unmeasured air into the engine. The performance of the engine at idle suffers greatly, and fuel economy and drivability problems may ensue. Here I share my experience of opening the valve and cleaning it to restore idle performance.
