Default Got CEL codes

My yearly smog is due and my car went to crud. The one is probably due to low gas for the last couple months, need to fill and see if it goes away.
The other failure, that's the fun one. I reflashed back to stock to see if that helped. Nope, didn't work. Can't even drive the car as it won't rev past 1800 rpm

According to my MY2005 Service Manual, DTC P0605 can occur for three reasons: 1) ECM calculation function is malfunctioning, 2) ECM EEPROM system is malfunctioning, or 3) ECM self shut-off function is malfunctioning. Failure 1) causes the system to go into fail-safe, or limp, mode, which is what you're seeing. For any of the listed faults, the only correction listed in the Service Manual is to replace the ECM.

Is there any way you can completely wipe the ecu? I know coming from a computer guy standpoint that a clean wipe usually puts all the memory back to like it was out of the box.

so I found a rebuild service. They test, fix and reset the ECU for $100

i flashed mine back to stock, removed the tune completely hoping it was my tune that got corrupted.

Better than a whole new ECU.

In theory, no reprogramming required.
