CEL codes P0172 and P0325
I just replaced the coil and wires in my SVT and after running absolutely perfect for about 60 miles the CEL came back on. I know they're codes for running rich and a knock, but after changing the Knock sensor back in July that code went away. Is it already bad again?! Any input would be greatly appreciated

Hi Steve! you need to check to see if you have a vacuum leak in and around the engine. having a vacuum leak will cause P0172 and possibly the spark knock on accel. hope that helps.

Thanks! Where would the vacuum lines be? I know there's one by the firewall, but are there more?
