I think there is enough room to slide a pan underneath, yes. The fuel line may be running under some wiring and/or hoses on the driver side of the engine though. I can't remember for certain, so take a look what might be in the way there. When I rebuilt my engine though, I never even disconnected the fuel rails from the fuel line, it was easy enough to work with.

And yes, if STFT is consistently negative, it will drag down LTFT to be negative with it. I too am not sure why UpRev would be showing that fuel trim at 100%, something to keep in mind maybe if you end up talking to them.

Just to update everybody who's following... there really is no update lol. Had it towed into the shop on Jan 10th, they were backed up and didn't get around to pulling it in until the 13th. They checked the injectors and found no issue there, sounds like now they're looking into the VIAS system as there was a minor improvement after cleaning some carbon and oil out of that area while the plenum was off.

Guess I can feel better about my diagnosis skills if its taking the pro's this long to figure out 🤣

Final update - She's been diagnosed and fixed!

Was a clogged secondary cat. Not sure how, as I spent an hour coring out the one side that was clogged, and I would've sworn on my mother's life the other one already had the honey comb missing. But I saw the pictures they took of the clogged honeycomb myself, maybe I had too many beers that day 🤣

Regardless, shop cored out the other secondary and she's running great with the only CEL's now being P0420 & P0430 from the missing primary cats. Once the weather gets a little nicer I'll get under there and add some spark plug non-foulers to hopefully get rid of those codes.

Thanks for that link. In the past I've used these: https://www.autozone.com/ignition-t...-plug-non-fouler-42008/730543_0_0?spps.s=2173

But I like the stainless steel and the option for an angle. Plus I wouldn't have to drill them out to fit the O2 like you do with the Dormans

I'll have to crawl under there and see if I need the angled ones, I'll definitely update once I get em installed.
