So since my motor sucked in a mouthful of water the other night it hasn't been running right. I've changed my oil, run a gas treatment flushed everthing and it's still sputtering. So, I checked my codes and this is what I found :

1.) Code 7- TP Switch
2.) Code 23- Knock Sensor
3.) Code 72- Cylinder 2 misfire or random fire
4.) Code 74- Cylinder 4 misfire or random fire

So, I'm running nitrous but haven't in the past few weeks. My question is what the hell do I do ? Is my motor blown from the huge puddle of water I went through ? I need some guidance. I'm pretty confused. Is it worth getting fixed or should I just get a new motor ?
