Van hesitating when in park

Hello, is this an engine stumble when running, but it's not happening while driving down the road? I can only think of air, fuel and spark influences to engine performance that may cause usual running. Spark plugs and related ignition wires or coils should be checked. Air hoses from the air box into the intake manifold should be checked to make sure they are intact and not separated or cracked. The PCV system should be checked to ensure no vacuum leaks. Hands on evaluation is best; seek guidance at a local shop near you. https://repairpal.com/auto-repair-near-me
