thnaks jim, well thats good to know that its not internal...as for the sputter'n it like it wants to stall but doesnt. it could be in park drive doesnt matter. But when in drive its like it looses power, it'll kind of buck a bit, maybe chugg'n might be a better word to describe it. but it will go away if i wait it out or try rev up the engine. im thinking of doing a tune up to eliminate some stuff.
