`92 Ve Engine......At idle..when I do a power balance test on the front three cylinders I have no change at all, no stumble, no nothing. Spark is really weak to nothing.So, Bad that it is not combusting the fuel and leaking thru the exhaust manifold to y-pipe conection. Rear Cylinders are working fine.Check thru the manual and said to check the power transiter....?? what would cause very, very weak spark.....
