Hey guys I have yet another question. My ef with a d15b1 stumbles when I take off from stops most of the time. When its stumbling I can hear the engine ticking but its definetely either losing spark or fuel, and i cant tell which. It had trouble passing smog last year and it was incredibly high on NOx most of the time, and then it would change up and be running rich. most of the time when its running I can smell unburned fuel out the exhaust. Also when its doing its stumbling act, it has no power at all and will jerk and stumble until i almost floor the pedal then it takes off and drives normally. I have done a tuneup on it, (wires, cap and rotor and plugs.) and i have also tried changing the distributor to a known good one. I even put in a known good ECU. Any help would be greatly appreciated, also if you have any questions for me about my car please feel free to ask. Thanks!
