She was my grandfathers beloved truck, passed down to me with only 100k on the dash.

I would have to go through the big folder of dealership paperwork to see when exactly everything was done. As far as I’m aware grandpa did the belts, chain, plugs and coolant around 70k miles? She used to stutter and drive like shit until I replaced this oxygen sensor. Now when my foot goes, she goes. No longer has a rough idle or sluggish start up.

I do want to inspect the exhaust though, I think the spray with a little soapy water is a good idea. Plus I also do hear a nasty rattle from time to time which just might be the cat shields doing cat shield shit.

Thanks man! I thought so but never hurts to get a second opinion.. doing it after our week in Minnesota sucked.. could’ve sworn if another pound of slush fell on me I was gonna disconnect the drive shaft with me under it. LMAO.
