Codes p0171 & p0174--Please Help
I have a 2014 corvette..
Last month i removed my American Racing Catless long tube headers and custom tune in preparation for getting my 2016 z06. Car was running perfect until yesterday i was cruising at normal speeds at low rpm's on the highway when a check engine light came on. The car ran normal and i made it home without any problems. This morning when i started the car it started a very rough idle so i immediately turned it off and just drove my Truck to work.. Now i checked the codes with my intune dyablosport and the codes p0171 and p0174 are shown. The car now starts and soon after it idles rough and turns off.. On research i see that those codes mean lean bank or misfire on older chevrolets.. Has anyone had this problem or know what could be going on? Any help appreciated!

After taking off the spark plug covers and checking all the spark plugs and spark plug wires i started to check all the electrical connections and i realized that the the stock intake was half way apart.. I put it back together and tighten it and problem fixed!!!
