What does the canister purge solenoid do in a charcoal engine?
The EVAP system traps this vapor in a charcoal canister and recirculates it for use as fuel for the engine and prevented from polluting the environment. The canister purge solenoid — also referred to as an EVAP canister valve — is responsible for “purging” the EVAP system by acting as the switch that allows the vapor into the engine.
Can a bad vapor canister cause rough idle?
Usually, when the purge valve is to blame for the rough idle, it will cause a vacuum leak which will impact the idle speed. If you have a vacuum leak that was brought on by a bad vapor canister purge valve, then you will probably have difficulties starting your vehicle.

Poor Engine Performance On top of a rough idle, a vehicle with a failing EVAP canister purge valve will display signs of poor engine performance. The engine may feel like its running “weak” and won’t generate sufficient power for acceleration. Accelerating will feel like you’re pressing the pedal down and moving slower.
