New Yaris owner from Texas

[sarap]

after installing it i gave up after reading countless threads on the cel light coming back on. In my younger days i would have just ignored the CEL and drove it not caring for it, but for some reason, perhaps error of install after multiple attempts to correct this, it just kept coming on, i honestly dont know what it was i was doing incorrect.
installed without MAF spacers, made sure all lines were clamped, etc. still no luck. I figured someone here with more patience could benefit from my lack of. Long story short i gave up on trouble shooting. Re-installed my OEM one and no issues with the drop in K&N. i bought the intake used, but the filter was spotless, no cracks in the piping, etc.
