You counted it wrong. Reading into it, it looks like you have a 173 and a 176 and a 54X

So, the o2s are throwing codes, and a fuel pump code from where the car stalled at some point.

ok will have to try again thanks

The 02 codes would explain the CEL going on and off.

Have you had the y-pipe off recently?
