Thanks for the reply.

So the multiple faults happened he second time around. The first time the generator code popped up and the only other code was oil level sensor missing. The codes pictured above appeared about a day and half after I disconnected the battery.

The n20 tmap is connected via an adapter that goes from harness b to a. I sprayed everything with maf cleaner and the pins looked good. But I will recheck the wiring, and in the meantime reinstall my stock tmap and map 0 Mhd flash to see if that makes the issue go away. The one thing I did not do when installing the tmap is disconnect the negative terminal on the battery. Other things disconnected and reconnected during that time were the maf, and all six coilpacks.

I will get to look at my car tonight. Haven't driven it in four or five days, so I will check the battery voltage and also take it out to get tested. I hope this is all due to a bad battery!
