Hey all. Considering I'll be doing this on my own. How much of a pain is it to replace the intake and the valve cover? I've got a 2014 Cruze 1.4L, and it's throwing the P0106, P0171, and P1101 codes. It's hissing air and rough idle. My warranty ran out in September. Just replaced the alternator, tensioner, and belt. I can already see this car is going to be a money milker.
