Ok I did it !
Well I ran seafoam through my V6 as directed. I SLOWLY introduced 1/3 can to brake booster vacuum line, put a 1/3 in oil and 1/3 in gas. Let it sit about 10-15 min. After starting her up she barly smoked, took her for a ride to make sure it was cleared out. From what I've read if the car doesn't smoke very much then it wasn't that dirty. Which makes me happy. Once I drive her for 50-75 miles I'll go ahead and put the new tune up parts on her and change the oil. Hopefully all this will return the throttle response I've noticed has slowly diminished.
