4 p0475
3 p0603 not to worried about(right)

The two you should focus on are the P1280 and the P1316.
The P1280 points to an ICP problem. Could be a bad sensor, unplugging it will tell you for sure. If it runs better with the electrical harness unplugged, then the sensor is bad.
The P1316 means that there are codes stored in the IDM. These codes will usually point to injectors or a bank of injectors that is causing a problem. The only certain scanners can pull those codes.

I'd guess the 1280 happened when you unplugged the ICP. Every time I've unplugged that sensor, it's thrown a 1280.
1316 means you need to do some more tests as Curtis mentioned. Can you do a CCT and buzz test? The other option would be to ohm the connectors at the valve covers. The most common issue we see that throws a 1316 code is a loose connector under the valve cover.
