03 4.2 egr
I have a 203 4.2 E150. I had a camshaft position sensor go bad and replaced it. A few days later I got a code for mass air flow sensor, cleared that and checked wiring. Next day got code for EGR flow and lean on bank 1 & 2. Vert light fluxuation at idle SOMETIMES, but half the times it runs fine at idle. Any ideas?

The van was acting horrible today, so i checked the codes thinking that it was the cam sensor again and this is what i have:
P0136 H02S12 CICUIT FAULT
P0401 EGR INSUFICIENT FLOW DETECTED
P1131 H02S11 SENSOR INDICATES LEAN
P1151 H02S21 SENSOR INDICATES LEAN
P0171 SYSTEM TOO LEAN (BANK 1)
P0174 SYSTEM TOO LEAN (BANK 2)
If anyone has any idea as to where i can start please let me know. I use the van everyday for work and cant afford to lose days on the road with a machanic.
PLEASE HELP!!
