hey just thought i'd pass it on but i have a 97 toy tacoma w/a 2.4 and a K&N Fipk II. ive been trowing codes for the past few weeks po171 (BANK 1 LEAN) anyway what i recently found out is if u run a k&n the oil gets on the mass airflow sensor, and cooks on to it. the fix, is to get some electrical contact cleaner and a q-tip 2 clean it very gently. I stopped throwing codes and all is right in the world. I figured most guys who sup up their bikes also do their ride, so if u have any questios feel free 2 ask. Drew
