Disconnect the battery for 10 minutes to clear the Code and try it again. There are several possibilities for the problem. The connector from the Crankshaft Sensor may Code a 355 when disturbed. This sensor connects to the coils and tells them when to fire.
If it is possible to switch the leads to the coils it would have the effect of moving spark plug wires on a Distributor cap. But usually the harness will only fit one way on most cars.
I do not know what problem you were originally seeking to solve, and the Crankshaft sensor may have been the original underlying cause.
Check the plug connector for corrosion or loose pins. If the problem does not go away, the wire loom may have a bad spot. The crankshaft position sensor can go bad.
Please rate my info.

So your codes are: Multiple random plus misfires on 1,4,8. Misfire during startup, and ignition coil E (cyl 5) primary or secondary circuit malfunction.
You said that four new coils were installed. Perhaps the coil to spark plug order and the firing order have been scrambled. The spark plug wires may be old and leaky--especially if they are the originals from 2003. You could have a vacuum leak into the intake manifold, the EGR valve could be sticking open when it should be closed, the fuel filter could be clogged, the fuel pump pressure could be too low or stuck at the idle setting, the fuel injectors could be dirty, and cylinder compression could be low (putting on the wrong size o-rings when reinstalling injectors will prevent proper compression.)
