Issues after intake manifold and valvecover fix

I hava a 2014 1.4l and had the valve inside the intake manifold and the pcv on the valve cover go bad. I purchased GM replacement parts for them and installed them a couple days ago. Since the install when I try to start the car it revs up to redline and then dies. After a couple times trying to start it I was able to get it to stay running but when it does, the idle is up and down and it is backfiring into the intake manifold. I have doublechecked everything for loose sensor plugs, and made sure all hoses are put back on. If I unplug the maf i can get it to run a little better but not much as it still backfires. Any help would be appreciated.
