Fuel pump is fine. Start up and idle pressures are where they should be, and exactly the same as when the Walbro was in. Regulator is also fine. It's something past the fuel reg...
I'll be getting a compression test done, asking to check the plugs and getting the injectors tested and cleaned. After that, it'll be somehow testing
MAF, crank and cam angle sensors. Not sure how, they're all so fucking expensive.
Going to ask on SOWA if anyone with a 08+ (that doesn't daily it) can lend me a
MAF sensor for 2-3 days to test.
