Hello everyone I'm getting an o2 sensor code ,o2 htr code, evap code, catalyst code, comp code, fuel code, and finally a po352 which is a coil pack, I took the truck in to my mechanic and he has replaced two coil packs drivers side catalytic converter and some sort of timing valve on top of motor on passenger side. It's a 2005 F250 fx4and these codes popped up after the work he did and I have been taking my vehicles to him for twenty years any ideas?

 

A person would need the actual code numbers. For example an "O2 code" could be half a dozen different numbers and they all mean something different and relate to each other in their own way.

 

Check the connection of the wires to each coil and make sure the plug actually clicks into place. A loose connection to a coil will cause RF frequency making the pcm confused with what it wrong.
