Is the engine suppose to shake when you unplugged coil pack?
I have p0300 code an my friend told
me it was the coil pack he unplugged
one coil pack at a time an one of
them didn't make engine shake is
that my faulty coil pack
That is correct that contact on the coil pack is not firing if it was the engine would shake like the other wires when removed. But first make sure there is power going to that coil pack. Now did your friend unplug the wires going to the coil pack or the power going to the coil packs ?
He unplugged the wire being connected to the coil pack it did nothing so that must of cause blinking cel an loss of gas an lack of engine power
That is correct.
