Mechanic's Assistant: When did you last fill the tank? And do you smell gasoline around the engine?

Maybe 2 hours before it started doing this i didn't really smell any gas

Mechanic's Assistant: Are you fixing your 9-3 yourself? What have you tried so far?

Yes i am its my sons car iv never worked on a saab not sure where to start i have just checked to make sure the fuel pump is working and that it is getting fuel to the fuel rail

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I think thats it

Hey how are you,I will try to help you with this issue

The DTC P0638 and DTC P1523 indicate a throttle body malfunction

Click on link to view trouble shoot and code description for both

The most common cause is TB body need replacement , it will take car in limp mode and want have power because the ecm is not sensing the correct tb body plate movement compared to gas pedal

this one on ebay used
