Will PVC valve make car sputter?

Yes, a faulty Positive Crankcase Ventilation (PCV) valve can cause a car to sputter. If the PCV valve is clogged or malfunctioning, it can lead to improper air-fuel mixture, which may result in rough idling, misfires, and sputtering during acceleration. Additionally, excessive pressure in the crankcase can also impact engine performance. Regular maintenance and timely replacement of the PCV valve can help prevent these issues.
