I just got an engine soon light and I get the P0171 and P0174 OBD codes...I replaced the o2 sensors a few days ago so I'm guessing its the boot intake..I'll update this thread if I can successfully repair it. It was suggested by my parts dealer to also replace the crankcase vent valve kit and also the idle control valve.mass airflow sensor and the disa valve.and a new tree air freshener.for the bs smell..any thoughts?.
.Thanks to all! !
