Have you done the tap on MAF test? Sometimes a wire or trace gets loose and they will be affected by vibration. Tapping with a screwdriver handle will cause a stumble when they go bad.

Haven't tried the tap test on this MAF, yet, but why would it have been damaged COINCIDENTALLY simultaneously at the same time the fuel pump failed, or just by (gently) removing it, to try a different one at the inspection station, when the X5 first quit running? I'll tap test it before I try one of the two $20 MAFs I carry as emergency spares.

If/when I find an extension hose for my pressure tester, and see that the pressure is dropping on turns, how does that reconcile with running rich all the time, now?
Does anyone know where to buy a 3-ft fuel pressure tester hose extension?

If, for some reason the new pump is varying flow, dropping the pressure way below 50psi, causing the stumble, any idea how I damaged the pump when first installing it? I found no apparent damage when I pulled the pump out to check the sender (with a multimeter), and loked it over for anything amiss, then carefully re-installed the pump in the deep well, with minimal effort, this time. Should I get a cheap replacement just to see? I just ordered a "free to me" pump, and will try it if necessary (or keep it as an emergency spare, or at least for components).

Obviously, I missed the inspection deadline 10-31-2025 (and 7-day grace period), so I'm now aiming for a solution that works well enough just to drive it to the "safety inspection" (sans emissions!) next October. I had a problem with my '09 HHR Panel, back in Dec. '15, when it was due for inspection, and it took me until Nov.'16 to get it inspectable, again. That's one of the reasons why I keep spare vehicles around (plus, different niche usages assigned to each one)
