[QUOTE="FunkyBoss, post: 5945525, member: 48847"] Ok, I'm almost 100% sure I found the leak that's been causing my lean codes that have plagued me for the past year, and it's actually in the IMRC plate. While I was installing a new FPR, I took water and poured it down where a bunch of fuel had leaked, in order to dilute it. When the water hit a certain area, I could hear water being sucked in to the intake. After hours of trying to zero in on the leak, I found that when I poured water on the plate's spring, it would suck the water in (see pic): [ATTACH=full]792189[/ATTACH] When I turned the valve by hand I could hear the air change it's pitch. Is there supposed to be some kinda sealant or gasket in there? Has anyone heard of this before? So anyways, I guess my options are to either buy new plates or do a true delete (I removed the butterflies) and get a tune, I'm just so tired of messing with this crap. I've had the intake off the car 4-5 times since I bought the darn thing a year ago. [/QUOTE]
