Hi:
My Father inlaw Lives In Alberta And Is A Oldtimer
His Cat`s Were Clogged So He Removed And Dissasembled The CatsThen Rebuilt And Reinstalled (Like I Said Oldtimer)
The Problem Is Now He`s Calling Codes
p0420
p1295

O2 Sensor`s Repectivly I Find

Im Wondering If There
Is There A Poor Mans Fix For This Issue
I Find O2 Simulators And Mini Cat Cells But We Dont Want To Pay For Those (Might Aswell Get New Cat`s)

Any Junkyard Fix Would Be Helpfull
Thanks In Advance

 

If he removed all the cats thats why hes getting the codes he need to at least install the cat right before the last o2 sensor in the exhaust theres no way around it
