Well I cleaned my maf, and poured some seafoam in when I filled my gas tank... car still runs well and nothing changed... although now I think about it I do notice when I am driving the car somewhat aggressive I smell a little bit of a gas smell idk if I am just imagining it or not but I notice it when at a stop light if I recently got into the throttle... any other ideas thats all I got for now....

The lean fuel code CAN be caused by a vacuum leak. It's usually from a bad line connected to the IM or FPR.

IM = intake manifold

FPR = fuel pressure regulator

Well decided to check for vacuum leaks today and weld a small exhaust leak turning into large leak up... while searching around for leaks I found that the main vacuum hose elbow coming from the block under the manifold was broke completely in half... so after a lot of bloody knuckles and few F bombs and couple hours finally got it out and back together with a nice heater hose replacement.... car seems to run a lot smoother but didn't clear my cel yet... will take it tomorrow and get it cleared hoping that was the problem... sure there are more to come as I am going back tomorrow to do a wheel bearing....
