No Stored SES codes? WTF?

For anyone who read my original thread..I dont feel like having this one locked up again for imature reasons...so I guess I cant really tell you when it throws the codes..

If Im on the car at a certain point it throws and SES code and stops pulling. However if Im at half throttle it will march right past that point and continue to pull.. oddly harder than it does at WOT. Many suggestions were to scan the car for a code and there are NONE!!! No codes stored anywhere. WTF?

The only thing I noticed one a O2 sensor being a bit lazy on occasion and sitting at ~750 then it would start reading again. BLM 128 on the right, but 114 on the left? I thought at WOT the car was in enrichment mode and didnt use 02 inputs. ??? Im really confused at this point. Anyone have any ideas? Everything else looks fine. Driving me nuts.

There is one more I cant quite remember
BPW - 2.8 on the left and 3.5 on the right ..I know the numbers for sure.just cant remember if it was the BPW or something else.. im pretty sure it was that though.

Welll Disregard. I may have found the issue.

Well..maybe a more simple issue here.. My radiator has a split in it and was presurized past anything ive ever seen.

Can you epoxy the plastic radiotor? or is going to take a new? Prices??

Also it didnt empty the pressure into the overflow?? was it the cap that caused this? Very confused.. Thanks in advance.
