Rough running 1986 Nissan D21, 2.4 z engine.

Asked by GuruWP2XS May 19, 2018 at 10:12 PM about the 1986 Nissan Pickup

Question type: Maintenance & Repair

Rough idle, misfire at low speed, high fuel consumption
and rich fuel odor, new NGK plugs, new wires, cap and
rotor, exhaust coil assembly disconnected due to igniter
failure but was driven like that for months before this
problem arose. Some days it seems to be fine, then it
starts all over again. Also has new engine temperature
sensor.
