Got a problem with my ole 3FE (yes it's an 80 but ya'll know the 3fe better). Every now and then the cruiser will just start to die on me, no matter what speed or how much throttle (if I'm on the throttle, from 1%-100%). It feels like someone is flipping a switch and it starts to die and it will have no power until I let off the gas, then it will sometimes re-occur when I get back on the throttle. Here's what makes my 3FE different: -EGR disabled but still present (plugged vacuum lines) -AI pump removed, air rail present but capped -Timing advanced to around 11* -Running 93 Octane -K&N Air Filter -PCV valve drilled out w/ mini filter, vacuum line plugged, intake line plugged, mini filter on front PCV vent -Cats gutted -AFM adjusted 1 tooth lose/rich Tune-up just over 1 year old including plugs, wires, cap, rotor, fuel filter, left bank O2 sensor, and thermostat. Where should I start?
