Crazy, but I just got code P1170 as well as my banks being too lean. Did you ever have your OBD rescanned to see if that specific code went away? I used a hoseclamp on my intake from the very start, but I suppose thats doesnt mean it couldnt have slipped off. I guess Ill have a look. Got a slew of codes this morning. All of them referred to my catless headers, but P1170 was the only concerning one to me.

Just got back from a weekend trip to Austin and CEL came on...same things with NO TRAC, no cruise control (which sucked)...I have a CAI and will be checking that dang hose in the a.m. Thank you all for the heads up on this also.

Follow up.....hose was off. Put on new clamp, reset CEL, all good.


Side note: I was wondering why it was making such good sounds under acceleration while disconnected?. Will a catch can retain that kind of sound?

catch can won’t affect the induction noise at all. I recommend the RRRacing AOS
