car wont start with COS#5

i upgraded my 99 operating system to an 02 operating sytem and the car runs fine. i loaded the cos5 file and then loaded the calibration file from my 02 operating system and the car starts for 1 sec and dies, wont stay on by itself or while i try to make it idle it dies. i even loaded the 02 operating system with the cos5 calibration and it runs fine. Can some help me out?

Start around post #10

As Beer says, you're too rich at idle, your B3647 shows AFR ~9 at idle (and also too lean at WOT).

thanks i went back and followed the tutorial and it worked like a charm.
