Thanks for your response! i have read over this site before posting actually, i really tried to get as much research as i could, i'm planning on new spark plugs, new distributer, new lines, new O2. and see if i can't clean out my throttle as well as the many other sensors that seem to contribute.
and there seems to be no real way of really narrowing it down. unfortunatly i will have to take the 70 dollar test again without knowing if the money i spent was still not enough, then i would need a new cat converter. i've also picked up a can of seafoam, figured it couldn't hurt...i hope. and my truck is having trouble shifting into 3rd! but i love it to much to let it go
