What is A.I.R relay on my 2001 Monte Carlo

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! The A.I.R. (Air Injection Reaction) relay on your 2001 Chevrolet Monte Carlo is part of the emissions control system. Its job is to control the air pump, which injects air into the exhaust system to help reduce emissions during cold starts. If the A.I.R. relay is faulty, it can prevent the air pump from operating, potentially leading to increased emissions and possibly triggering the check engine light. If the relay fails, you might notice performance issues, such as rough idling or poor fuel efficiency. Addressing this could help your car run smoother and be kinder to the environment!
