sr20det cutting out and misfre

[bmxer882x]

Alright so I've been battling this since day one. I cant figure it out.
Whenever idling it doesnt seem to have a miss but anywhere 2k and upwards i notice a small hesitation. Also i randomly have a huge power loss when driving. Feels as if i lose a cylinder. That doesnt happen alot but when it does my afr max's out lean.

Idling when warmed up it's idling at 11.2-11.5 which is way to rich. Cruising is around low 14's

So far i have:
checked the coils resistance trying to find a set to swap and test
checked fuel injectors resistance
checked the fuel injector harness voltage- fixed and all spraying
changed the coolant temp sensor
checked the tps voltage and resistance
changed the plugs to bkr6's gapped to .30
changed maf from sohc maf to sr
checked for vac leaks several times
checked for boost leaks with a homemade tester thing
im running a j4 ecu

Another thing i have noticed is there is a considerable amount of fuel in my oil, it has 1,500 miles and im going to change it this weekend.

Any ideas of anything else i can check?
