installed an injen cold air intake on my 09 es last year. the service engine light has been on and i've been places to see what the issue was. the code is p0171 and the mechanics i've talked to said its running lean and too much air is being pumped in without enough fuel. I was seeing if anyone has this problem, and has a remedy for this. i already reset the ecu, the mass airflow sensor...and found out that it was not the problem. i thought the injen was tuned to not have issues such as this one. if anyone has had similar issues, let me know. thanks!
The last times that code came up on my car it was the gas cap was loose and the filter on my air intake was loose and I tightened it up and it went away. Maybe try those if you haven't already? --- I am here: http://tapatalk.com/map.php?taalr2
Replace the filter with an aem or k&n. I know k&n has a thicker filter. Sent from my DROID2 using Tapatalk
I also have the INJEN cai and even the 4G69 throttle body upgrade... never had this issue. Start looking into getting a SAFC or do what these guys say. GL, bro!
