Well that's a sigh of relief that at the very least, my misfire issue isn't being caused by low oil pressure. I did a pressure test and changed the oil today, and got the results below once the car was fully warmed with an oil temp of 176°F or 80° C. Looks to me like the motor (as far as bearings and the gallery gaskets) is nice and healthy! I also sent out an oil sample for analysis to Blackstone Labs, so it'll be interesting to see if there's any fuel in the oil. That'd indicate an injector at least sticking open or adding too much fuel. At this point I think I am going to call the car fixed. I'm only logging 1 or so misfires every other drive cycle, so I'm inclined to think at this point it's normal to show a small amount of misfires like that. Can anyone confirm?

Idle pressure is around 22psi



Oil pressure at 2,000 RPM is about 64psi
