hi, i have an intermittent misfire on #1 cylinder when i cruise at high speed , i loose current at #1 coil and some time it recover the same day sometime the day after. i replaced the powerpack (new cdi 113-2285) plugs wires and spark plugs (ql77jc4) .1 new coil . i swaped the coils with the same result #1 cylinder dead.
fuel system ok 2psi idle,4psi high speed.i have 12.5 volt at idle. do you think the stator or the sensor can cause this problem?thank you for the help.
