2013 ls 3.6l v6 camaro
Hey, Scotty, I have a question the other day my car was operating normally but when I pulled into my apartment a stabilitrak and check engine light turned on. After running it a little bit I started getting a misfire , I replaced ignition coil pack 5 and all 6 spark plugs as I was getting a p0305 code initially. After replacement the car still misfired and was throwing a p228c, p0305,p0300, and a p00c6 code. I took it to a mechanic but he said his obd code reader wasn’t getting to the specific problem and to just take it to the dealership. With his tests though he thinks it may be a high pressure fuel pump , as I just learned these cars have two fuel pumps. Is this correct? Would that be the part I would replace?
thank you

what an absolutely useless mechanic. And don't go to the dealership either they'll just replace everything they can.
Please read our FAQ to see the basics to check for misfiring and let us know if that helps.
fuel pumps. Is this correct? Would that be the part I would replace?
Maybe. Is the fuel pressure too low?
The mechanic said he tested the low pressure pump and it was at a perfect rate but testing the high pressure pump it was low
