USA car? must I GUESS?
so you have 2 coil packs. ????
called wasted park
seems you typed the displacement wrong, !!! 2.2L is 4 banger...
1 and 4 fire as a pair
2 and 3 , fire as a pair , in series
so if the spark wires open , you loose a pair,
say #1 opens, you loose #4 with it.
they are wired in series.
if one spark wire grounds out , you lose only THAT spark plug.
but why would you get the odd pack to pack cross talk.
(assumes you have the HV wired right. correct?)
the packs cant be wired up willly-nillly.
this is the 2.2L coil pack.
and IS wasted SPARK system. for sure.
and can not be mixed up
the PCM is hard coded for 1,3,4,2 firing order.
and must be wired right. did you meddle here?
if you unplug the 2 one right , this must not make the 2 on left work.
pulling 1 wire, only kills the adjacent wire. normal.
see the pairs there, at the bottom see those hiddencoil packs mail coils molded to case?
if you are wired right and you have cross talk from 1/4 to 2/3 bank
the pack is bad.
by cross talk i mean, 1;3 effect 1/4 or the reverse.
