10-PCM is the category for PCM codes. It is always there. You have to display the codes that are within that category. First Push and Hold Options then while holding the Options button push the fuel button 4 times. The car will go into diagnostic mode and will proceed to the 10-PCM category first. If there are any codes it will flash each one of them for several seconds. When it finishes that category it goes to 20-TCS next.

Have you recently installed long tube headers and deleted the rear O2 sensors? Sounds like it. You need a tuner to delete the O2's from your computer. If that's not the case, the other common problem relates to a fault in the air pump system.
