Over 5-10psi it feels like it's running on 3 cylinders and sometimes it backfires violently.. When it happens I smell raw gas so I'm pretty positive it's an ignition problem. Sometimes the problem goes away for a little while before coming back. I have:
Replaced coil with OEM Bosch
Cleaned and gapped plugs to .030 (I was running about .035 before, thought maybe that was it)
Compression tested (150-155psi on all 4)
Cleaned a bunch of connectors
Cleaned the hall sensor/cap/rotor
Tried a spare MAF
Pretty much out of ideas.. The problem started happening awhile ago on a cold engine but it'd go away after 5-10 minutes of driving. Now it's all the time.
