Ok now I'm really at a loss

Checked the injectors hot they all rear around 15 ohms.

I even changed out the secondary injector relays with my spares and it didn't change anything.

now heres the kicker I was hammering on it this evening just now after I did this nice hard pulls untill around 5K and it stumbles but then keeps going but when Im around 60 in 2nd gear I get a SES light.

checked the code and Its damn 61 secondary port throttle system WTF
