Yes. A stuck purge valve:

Increases unburnt hydrocarbon emissions

Causes fuel vapors to escape directly into the atmosphere

Makes the engine run too lean o r too rich, affecting fuel economy

With Punjab’s Vehicle Inspection & Emissions Program VICS expanding, such faults could cause failure in emissions testing.
