engine problems

I have a 2014 chevy cruze 1.4 LT with 44000 and only 8000 miles on the head. Just had the pcv and valve cover changed. I drove the car today engine ran rough. Service stabilitrak and traction control message came on then service engine light started flashing p-0303. Ive had alot of issues with this car this is just the lastest 1. Any advice would be great. It seems like I keep chasing gremlins with this car.

That sounds like the well-known negative battery cable problem, at first blush.

Unfortunately, just a P0303 is not a lot to go on.

It'll be under warranty, as misfire is powertrain. More than likely the tech that did your PCV messed something up, or the negative battery cable issue. Also, if your dealership didn't replace the intake manifold for your PCV failure, go back and tell them to reference PIP 5159 and replace it.

Do not worry about the Service Stabilitrak warning, as that warning will come on whenever certain priority powertrain codes come up, because Traction Control/Stabilitrak - the fun police modules - have their abilities to do their job hampered by powertrain faults.

8000 miles on the head, We had an overheat situation?
