DODGE RAM SPARK PROBLEM

1989 Dodge Ram • 206,148 miles

What happens if the van is running sluggish and you check the spark plugs and all of them are producing a spark but only 4 of them make the van idle down to the point where it will cut off? Is that the cylinders and if so how much of a repair job is that?

What is litre size of engine? You did a cylinder balance test and only 4 cylinders had any effect on idle? The ones that had no effect are considered dead cylinders. Check Spark--fuel--compression. Are there any applicable mil codes?
