Have you tried validating PID's?
Open the scan tool and go to the pic in the toolbar of the page with the green 'tick' on it.
Click that icon.

It's gone or is it X'ed out?
Sometimes valid PIDs will have an X through them until you start logging.

Validated PIDS also checked old log files the PID is validate as well it is also X out check out this log file. It is a log file from before full reflash. I have seen some threads on changing to a 2002 operating system. I don't think this has any thing to do with losing the pids? I am going in to the shop today and will try a full new reflash with the tech 2. and see if the Vin and the pid shows back up let me know any other ideas.

THANKS CHRIS

That log shows the PID is valid and data for MAFFREQ.

Well reflashed with tech 2 and all is fine now don't know what hapened but is very strange.

On the last post yes the pid was there. After it was full flashed then it was gone. I was saying if you look at the air pids it is slected as well as x out
