Is someone on that can help

I need to post my datamaster file so all these guys can see what the heck is wrong with my car but Im not sure how to post the file.
Anyways without loading the file onto here these are those codes: MALF 26: CCP ELECTRICAL FAULT
MALF 27: EGR ELECTRICAL FAULT
MALF 29: EAS ELECTRICAL FAULT
MALF 66: A/C PRESS SENSOR OPEN/SHORT
MALF 77: FAN 1 FAULT

Im really overwhelmed by all of these codes im hoping there not all seperate problems in themselves. We took out the ac so that might have something to do with the 66 and im not sure if the egr is throwing a code because of the headers. no idea whats up with the fan or the eas electrical fault or ccp electrical fault.

This might help too.
A/C pressure is at -13.1
EGR DC is at 0.0
CCP DC is at 0.0

Both the egr and ccp jump around throughout the testing from 0 to 100.
Also it appears as though im running rich down low from 800rpms to 2000rpms after that i'm fine. Thats for both Right Lterm vs airflow as well as Left Lterm vs airflow. Just to use this for an exemple on the right lterm vs airflow chart cell #35 has 1099 hits. thats the most out of the cells though. if you need any information on this just ask....or i can see if i can send the file to someone with more knowledge.
