Wants to quit running and jerks as though it stopped. what is it?

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 vehicle. Since you’ve already replaced many components on your P30 and the problem persists, the issue could be electrical, like a failing ignition control module or crankshaft position sensor. These parts can cause erratic behavior, like stalling or jerking, without setting off consistent error codes. Additionally, a faulty or loose ground connection could also cause intermittent power issues that lead to jerking and stalling. It might also be worth checking for any vacuum leaks. Since intermittent concerns like this can be a safety issue and are complex to diagnose, it may be worth consulting a trusted repair shop in the area. 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!
