Hard to start, found problem. Now Why?

Got one of the Wagner adjustable PCV valves. It used to be that there were CORRECTLY ENGINEERED pcv valves for all cars but over the years the selection has been reduced almost to the point of a one size fits all situation. Even if you could get on that was made for your stock engine if you've changed you cam, intake, heads, carb etc, then even it's not right. This PCV is completely adjustable and has adjustments for both idle and cruise. It's not cheap but it is adjustable for YOUR car
