that's interesting Sadeed that a spark plug would have to respond to the battery!! I've all
my cars and not one responded to battery. I don't know who told you that.. the battery
helps the starter start the motor thus it's ability to hold a variety of cold amps to crank the
motor to begin with ( higher cca in colder areas. In hotter months 650 cc is fine. STAY
AWAY from dry cell battery).
So, I would try a couple of things here.. first of all, the car was operable before disturbed
circuit took place ( most likely fuel relay). For a car that old, the relay is most likely old ( it
doesn't help that heat and electronics don't mix anyway). Relay is a black box in your fuse
box area and is usually identified on cover. This is cheap and inexpensive to replace that
box. Second idea, take your spark plug wire and replace them alone with with coil wire ( I
did this same thing with my Mercedes and got plenty of rush out of my acceleration ( but
DONT change the plugs). After those 2 steps, if the car runs better then you know you
found the problem was one or both. After that is done I would find a place to get a
compression test to see if anymore work needs to be done to it and then come back to this
article ( I will se you respond).
Third idea, if the car still acts up I think I might focus a little harder on the camshaft position
sensor. Another story for another day. One step at a time.
by the way, the crank sensor reads the flywheel then tells the computer when to send
spark to the ignition coil. The battery has nothing to do with that. BUT you already have
crank so it's not CPS issue. g'day
