Hello everyone, this is my first post on the forum. I know this has probably been visited in other posts but I've been looking around forever and I need to fix this before inspection. So I built myself a nice spectre intake and I was getting a p0171, and after some talks with mechanics I made sure I had the crankcase vent in the closed system again, I extended the tuning into the fender and added an air straightener, and the p0171 went away, but now I'm getting a p2177 and p2187, as well as a p0101 and a p060c which isn't looking good. I know lean codes are normal, but this seems like something other than my intake is causing a problem.... any insight would be greatly appreciated.

 

Put your standard airbox & intake back on, clear the codes, disconnect your battery for 10 minutes, start it, let it warm up, go for a drive & see if you get any codes. Go from there.
