I just found out my K&N was ruining them (too much oil), but my 3rd one right now won't let me hold an idle. I either bought a bad AFM (getting code) or maybe I need to adjust the screw....
Oil will destroy the electronics on the AFM and your car will not idle or excelerate properly. replace the eletronic part of the AFM and repair any boost leaks.
The adj. screw will help you to raise boost cut and adj idle mixture with 550 injectors +the lexus AFM.
