Engine Performance problem
1985 Nissan 300ZX 6 cyl Two Wheel Drive Manual 195000 miles

i have cleaned the injectors, replaced fuel filter, fuel relays, distributor cap, rotor button, spark plugs+wires, starter, and established the pump is in working condition. I have adjusted the timing. The car will idle for a moment then it slowly drops in rpms and while driving it will randomly stall out and sputter when u attempt to accelarate
