Will purge solenoid cause engine misfire light?

Yes, a faulty purge solenoid can potentially cause an engine misfire light. The purge solenoid is responsible for regulating the flow of fuel vapors from the charcoal canister to the intake manifold. If it malfunctions, it can lead to an improper air-fuel mixture, which may result in misfires and trigger the check engine light. However, misfires can also be caused by other issues, so it's important to diagnose the problem thoroughly.
