And because fuel pressure is good, I'm thinking air measurement. Guessing a messed up MAF (even though I cleaned it) or a messed up throttle body... either dirty, or failing. I don't like throwing parts at a vehicle (especially while unemployed) but I did purchase a new MAF online yesterday, figuring I can just resell it as new if it doesn't help and lose very little money in the process. Today or tomorrow I might get on top of the engine, remove the metal supercharger intake tube and clean the TB.
Overall, the vehicle runs great with lots of power, and fuel economy is as expected. Seems to be intermittent, which is what is making it so hard to track down.
Maybe I should have listened to all of you. Lol.
