Well I had been knocking my brains out fo the last month or so trying to figure out what was causing a check engine light banks one and two lean. I was thinking new chip dyno, FMU issues,o2 sensors something expensive, well I put a K&N filter into the drivers side pcv for a unrelated fix, took the car for a ride and almost instantly feels better like I found 50hp, and after riding around for about a 1/2 hour the check engine light goes out! Has anybody else experienced anything like this.
