Car felt sluggish tonight when I did a few races so I decided to log a little on the way home.
I started logging and notices that all my ltfts were 0's. Im like wow.... Well then I noticed that the 02's were hanging where they do at wot...I looked at the a/f ratio and it was running super rich all over the place...I went wot and got lots of knock and it was hitting 970 and 980's wot.....
Any Idea whats going on?

PE requires you be above enable MAP and above enable
TPS to be active. However you can be open loop from
other things, such as cat overtemp (COT) or some other
system fault (O2s, maybe other emissions things).
Look at TPS reading to be sure it's not saying WOT,
pull codes and see if any unusual new ones have shown
up (the SES light may not illuminate until fault is present
for a couple of starts, etc.).

Well things are back to normal now. I have cot turned off. The car was warmed up and tps was working.
The only code i was throwing was the insufficent switching of 02's...Maybe that was it.
