Njcruze

Hello first time poster, I'm in a crazy situation with my 2014 Chevy Cruze. I had a tranny flush and oil change done a few weeks ago ,then recently this past weekend all my lights went on and the car started to idle and drive very rough. Brought it home hooked the computer up it threw 14 codes.stsrted from the top we replaced the pcv valve/ valve cover, new spark plugs and coil pack, and the whole entire intake manifold assembly including injectors throttle body the whole 9 yards. Also did a compression test everything was running good. Replace all of that and I'm still getting a cert rough idle and it now rough drives as in weak acceleration vibrates and shifts very hard. We are really scratching g our heads on what it can be. Can any one help

Really strange situation, from what I read, then you tried a lot, bought new car spare parts , and nothing helped. I just did not understand everything you did, you yourself? or drove to the auto repair? If you yourself, then maybe now it will appeal to specialists?
