Could be a stupid MTI Air Lid question but...... Could the rubber gasket that goes around the Air Box Lid connecting the Lid to the plastic housing actually be the Air Leak giving me the codes PO171 & PO174? It only happens when I have the SLP MAF & Bellow installed, not when I have stock MAF & bellow. The MTI Lid stays on the car all of the time. I noticed the cheesey rubber gasket's double sided tape screwed up and wonder if a slight improper setting of the Lid could cause the SLP MAF to send the code or not.

It also doesn't take much of a leak to really throw the O2 readings off. I had a band clamp leak on the passenger side header connecting to the y-pipe. It was making my right bank (LTFT) +10 higher than my left. It didn't make any noticable ticking sounds either when it was leaking.
