thanks trigger, actually, i got my exhaust fixed the other day while i had my chrom tips put on, and its running 15 times better than it was, still not quite rite, but i can actually keep a decent constant speed now...so im hoping that fixing the exhaust 100% and im gonna change the spark plugs, put new manifold gaskets on, and do a tune up of sorts and hopefully it will be good...

any way that my problem could have been a back pressure issue?
