It chugs when you start up a hill

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Park Avenue. When your car chugs or hesitates when going uphill, it could be related to several potential issues. It could be a fuel delivery problem, such as a clogged fuel filter or a failing fuel pump. Another possibility is an issue with the ignition system, such as worn spark plugs or a malfunctioning ignition coil. If the engine isn't getting the correct air, spark, or fuel, it will struggle, especially under load. A dirty air filter or a problem with the mass airflow sensor could also lead to similar symptoms. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
