This poor Cadillac BARELY runs...apparently the entire front bank of cylinders has NO SPARK.

For some reason there's a new catalytic converter installed on the front bank too...as well as cam solenoids, sensors, and other parts...hmmmmm

ECM is setting some very specific circuit codes, so we have a good direction to start.

Can we get this Cadillac to run on all 6 cylinders without throwing any more parts at it?
