I've just recently installed an AEM intake. Everything's pluged in that i remember no hose's are out, yet the light came on. I went to autozone and they diagnosed it.
Results:
4 triggers.... 2 in bank 1, 2 in bank 2
all saying that i'm running Lean.

does anyone have any ideas about the fixes for this ???

Easy fix first - Try cleaning the MAF meter by the air intake with some electronics contact cleaner.

Post your car, engine and year, and code on the ECM

ok i'm a lil new that this, but what is ECM??

ECM = Computer [post the code(s) that says you're running lean]
