After a fast idle would clear up
Replace all 4 injectors now have no fire on 2 and 4 inj. Wires.
Will start, takes a hold lot of cranking. MISSING BAD when starts, maybe running on
1 and 3. Could this be the ECU

# 2 and # 4 injectors shares the same circuit. If you have battery voltage to the Black/Yellow check for continuity for the Light Green/Black wire to the ECU Connector #2 terminal "V". If continuity is available, the ECU is most likely faulty.
