hello
could someone help me troubleshoot my 2002 cavalier 2.2 L, it has intermittent spark, i can pull the wires at the coils and i can see good strong spark from all four post and then again no spark at all. the car will start maybe 2 times out of 5, the other times it only spins. I have replaced coils and crank sensor.
thanks
my 2004 does the same thing
