My ratios are everywhere. The other day it was fine. 14.3 - 15.5. Yesterday as I was cruising it was at a steady 10.0 the whole time. I was stalling at red lights trying to get the car home. While coming home I accelerated from first to second and the car lost throttle power or like it just bogged down, then everything was normal again. What is causing this issue? Bad fuel supply? Bad maf? Both? Tuned for 94 octane. I only use 94. Thanks for the help ladies and gents. 2003 supercharged mustang Gt.

Thanks for the info, macgyver. Pressure is regulated and fine. The car idles rough and stalls now. It’s just so strange that it works some days and the others it’s hard to drive.
