Running too rich and too lean.

When I start my car the injector display on the AVCR goes insane. It jumps arounduntil you let the car wam up. While driving the car runs reallyrich and myfriends said that it shoots flames past my bumper. However at high RPMs it runs way too lean and the engine knocks. My friends say that the Apexi S-AFCII will help solve the problem but they are unsure since they have never messed with an MKIII. Would the S-AFCII work?or a diagnostic?
