cold start engine knock and tap... help
ok guys. im lost on this one. the coldest night here in nj all year. temp is 25. i go outside and start my car. vanos and a tap knock sound while car is running. ses light came on right away. plugged in my mac obd2 reader and got codes p1519 , p0325 , p1175. i looked up all these codes and know what they mean. but does anyone know, or have had experience with the similar codes all at once. p1519= cam position actuator , p0325= knock sensor , p1175= fuel trim actuator. just tring to figure out what needs to be done or changed. my car always had the vanos noise. now its just a little louder. sound seems to be coming from the passenger side. thanks for your help / knowledge in advance
