One of my friends has a Tahoe which was having the same symptoms and he told me it turned out to be a dying upstream O2 sensor. I do have a shop vac so I'll give that a try after work and report back with my findings.

4.2 I did reset it for a drive from Lewiston to Moscow and back and it topped out at 11.5 I will say it does feel like I'm getting gas fairly often considering the little bit of in town driving I do. I don't personally feel there's a lack of acceleration or power. It'll squeal the tires from...

I recently became the owner of a 2005 GMC Envoy XL. It runs and drives just fine however it does have a P0420 that comes and goes, and my fuel mileage even on the highway won't surpass 11.5 mpg. Is it possible it has a clogged cat? How would I check?

Two different gauges and they're within 2 psi of what my tpms says

Even if it was a temperature drop, surely that wouldn't be causing me to lose almost 20 psi? I thought at first someone was messing with me, I've known people to hide balled up foil in valve stem caps, but there's no signs of tampering.

This just started a few weeks ago and I wouldn't think much of it if it wasn't for the fact I'm losing air in EVERY tire simultaneously, and at a quick rate. I usually keep my tires between 35-40 PSI but at least once a week recently, they all get down to 20-25psi or so and all at roughly the...

I bought these off eBay less than 6 months ago however here's the top of one of the filters with the code

Bought these for servicing my coworker's daughter's Corolla but she recently traded it for a Ford Explorer so I no longer need these. Cross-reference list is in the pictures. Make me an offer for the lot or I'm also open to trading these for 7317 size filters that I can use on my Pathfinder...

I wouldn't let them touch my lawnmower after seeing this. And yes it's the correct filter. HP-1010 same size as a 7317

Yes, decades old. Both UOAs were using this old oil. I don't have any more in my stash and my current OCI is with newer oil.

I'll have to pull it apart tomorrow and look, but from the outside everything looks fine

I'm assuming this goes back to when my transmission got replaced last year, but literally none of the brackets for my power steering lines are bolted in place. So my metal lines were hanging down and on a long enough timeline, rubbed through and began to leak.

No, right now I'm running super s multi flo 10w30 syn blend

Everything looks fine 5

With my last OCI I finished up my old stock Quaker State API SJ 10W30 I had on hand. I had about 4500 miles this time, which included a decent amount of towing plus "spirited" driving. The results this time seem concerning so I'm interested in what you guys think. Picture attached.
