In another post, I talked about my P0420 and P1283 codes. I have read posts about cats and O2 sensors, and using sensor standoffs, etc. etc. I have decided, after spending over $4000 to rebuild my engine, to put another $500 into it by replacing both cats and all four O2 sensors. I suspect that at least one O2 sensor is bad and the cat may be shot as well with about 140K miles on the truck (and gas mileage is terrible). With a new engine and a tranny that seems to be working perfectly, I can’t see shotgunning replacing parts one at a time until i get it right (and later have another part go bad) when I can replace them all and be done with it.
So, although I am not a master mechanic I plan to do the work myself. My engine rebuild was done by a friend who is a master mechanic and he did it for free. But, now he has moved to Oregon. I am 79 and have done most maintenance on my vehicles all my life and saves thousands of $$ in labor costs. If anyone has any advice on the easiest way to replace the cats, I’d love to read it here. I don’t have a lift, just jacks to raise the front end some. I plan to drive it up on 4 ½” high ramps I made, then raise one side at a time much as I can, put in support stands, then remove the wheel liner, wheel and tire so I can get to the cat on that side. So far, do I have the right approach?
Then, would it be easier to remove the O2 sensors with the cat installed or after it is removed? My parts will be here next week and I’d like to get right to work, but sure would like to know if I am doing it right.
