Disconnect the battery (unless you did this for the wire/plug change)
and REALLY make your PCM relearn the idle strategies.
Adaptive learning is what its called, I believe.
btw, the coil pack sparks TWO cylinders at once the
the need for only 4 wires on the power connector instead
of 7 (one ground)
One cylinder sparks at TDC compression stroke
and another also sparks at TDC on the exhaust stroke.
Tachs and shift lights need to be set on 3 cylinders
instead of 6 for them to work correctly.
