Ok, found a quirk that I found really odd. I had an a/f gauge prior to the turbo install, always worked fine. When I put in the turbo I had to disconnect the black wire that ran to the o2 sensor for the a/f gauge, and I never touched the purple wire. I reconnected the black wire to the o2 sensor but the gauge doesn't work, just sits pegged all the way rich. I traced the purple wire going into the hole in the firewall, but didn't see where it was going to inside the engine bay. I just took a quick look, so I'm going to get a better look tonight after work to see where it goes. Anyway, last night I was adjusting my side view mirrors and the a/f gauge lit up like a xmas tree! Everytime I touched the little pad to move the mirror, every light on the a/f gauge lit up, odd! Anyone have any ideas what might be causing this? I'll report back when I find the culprit.
