I recently installed a cai on my 2012 Civic LX coupe. I went with one of the 3" kits and some spare 3" pipes from Autozone, and I'm using a Spectre air filter. About 60 miles after the installation I got a Check Engine light, and the iMID displayed "Check Emission System." I took it to Autozone and had the code checked and it said that my engine was running lean. The guy at Autozone didn't know much about the newer 2012 systems so I'm running a little blind here. Any help would be appreciated.
