It's cheap and easy and won't harm anything even if it doesn't fix it, it's worth a try. DO NOT use an engine flush (the type you put in just before changing your oil and let it run 5-10 minutes). Those chemicals actually break down the lubricity of the oil and can do MAJOR engine damage. The add-in detergents I listed above stay in and you let it run for the life of the oil change.
Thanks for your help guys. The car is doing alot better. First I put in a bottle of lucas and a can of seafoam and that is helping because now the lifter is starting to unstick itself. Hopefully it goes away for good.
