98 F150 4.6L Errors
I am helping a friend work on his truck and I used scantool to come up with the following codes, while i can see that there is an issue with the EGR valve I believe that the truck is in limp mode causing some of these. Anyone have any ideas.
This truck at this point is running very poorly.
P0401 Exhaust Gas Recirculation Flow Insufficient Detected
P0304 Cylinder 4 Misfire Detected
P0308 Cylinder 8 Misfire Detected
P0171 System Too Lean (Bank 1)
P0174 System Too Lean (Bank 2)
