Default po174 and po171

my car was completly stock until I put on a slp lid and a speed inc hi flow filter.about 30 miles later the ses light appeared so i went down to auto zone.so now im running lean on bank1 and 2.that was about 2 weeks ago.

they said it might be the iat sensor or maf sensor,so went home uhooked the battery,cleaned the maf sensor,hooked everything back up and still the light came back up about 30 miles later.did this step twice light still came on.

did some search on ls1tech,looked around for any leaks where air could be sneeking in and found nothing,so i decided to take my old filter off the ss and put it in the z just incase the new filter was oily,42 miles later the light appears.wtf is up.

I did this mod to my ss 3 years ago and never gave me trouble what gives.

would it hurt to drive the car around while i try to find the problem?what if i made wot runs would that hurt it?

INPUT PLEASE,IM LOSING MY HAIR OVER THIS.
