I Need Help With Codes
1996 F150 4.9 4x4
I have the following codes
EGR flow insufficient
Bank 1 & 2 system to lean
Manufacture control fuel air metering
Is there a common link between these codes like maybe low fuel pressure?
Gas mileage is low only 8 mpg with 3:55 rear end
Thanks

check egr valve is not leaking by putting vacuum on valve and see if vacuum holds, if not repalce egr if it holds , you might wanna take the throttle body out and clean it with carb/throttle body cleaner, make sure all the passages are clear blow them with compressed air.

Just for future reference you should always post the exact codes you get, not just the code description... some documents are poorly worded and distort the meaning of the code.
In your case all these codes are likely connected to an EGR problem. The code reports low or non-existant flow so it could be a sticky or failing EGR valve, or a broken or cracked vacuum line, or a malfunctioning EGR regulator. Figure out what is causing this code first, then clear all codes and see if any come back.
