So my father has a Neon SRT4 that he is having a problem with. He is driving back home from being out of town and he just heard a loud popping noise and experienced an instant loss of boost. Boost gauge shows 18lbs at idle but does not move when he gives it gas. Also, the car has an HKS SSQV V1. Until now it seemed to be working properly but after the popping noise it does not make sound at all. The car has a constant whistling noise when driving it. It sounds to me like the BOV is stuck open causing him to lose boost pressure. Anyone have any advice? He needs to drive the car home but I don't want it to become damaged. Need help ASAP! Thanks.
