2014 impala 2.4 p0011 p0016 p0089 p228D
Hi, I’m new to this. So, here is my problem I was getting a p0016 p0089p228d so I replaced the timing chain set, cam phaser, cam sensor, high-pressure, fuel pump, fuel pressure sensor on the rail, and also changerd the intake solenoid. Put fresh oil. The car will run good for like 5 minutes, then start running bad sets the codes and goes back to running normal. But has the codes and power reduced. All the lobes on the cam are good, no engine noise. I’m so confused as to what else it could be? I am a mechanic at a shop, so I can do any other testing if there is any needed. if anyone has been through this please help!!! Thank you so much in advance!!!

Check the engine oil pressure when oil is at operating temperature.
2. Erase the DTCs. Using the scanner, command the CMP Actuators to varying positions.
3. If the CMP Actuators do not go to the commanded position, try an oil flush.
4. Verify the crankshaft gear is not worn. Inspect for a loose or jumped timing chain.
5. Verify the position of the reluctors on the camshafts. Refer to GM Document PIP4548*.
