im gonna take my friends fuel rails, injectors and FPR and put it on my car to see if theres a difference, also whats the possibility of maybe a crank sensor being bad causing it to run lean? i doubt it but just a thought

A bad crank sensor would not cause a lean condition. It would cause the motor to misfire and stall.

Anything that will cause a misfire will show up as a lean condition because the oxygen sensors only sense oxygen and not fuel. They detect a rich condition by detecting a total lack of oxygen.

But yeah considering you haven't mentioned any misfires I'm gonna say your crank sensor is not bad. Nor do you have a cylinder going out since the only way that would cause a lean condition is if it were misfiring.

well im not throwing a misfire code but i swear it sounds like i have a miss ill put an exhaust clip up maybe you can hear it its almost like a dun dun every few sec im gonna pull the plugs out sunday and do that stuff with my friend and ill put every thing up. but at full throttle i cant tell, i got off on the highway today saw an audi and a Beamer being drove by a 20 something douche they were racing hard dropped it into 3rd walked em like they were standing still. prob shouldnt been hard on it but the situation was too good to pass up haha
