yeah, thats way to lean.. very unsafe. i'm not trying to make you spend money but your at the point of hurting your motor.. I mean that lean is brutal to the head gaskets and pistons.. the gaskets could already have been compromised , hense more knock... u said you have a adjust fuel pressure regulator right? if not yet, pull the vacuum hose off the regulator and plug it. you'll be in better shape.
