anyone?

small update,

if i start it up cold and drive around town, it seems to want to chug but don't, its only really after a 20 mile hi way drive when i get off and back to local streets, it chugs. like i said at 30 mph, but it did do it at 40 yesterday. im so lost, i need some help with this one.

my muffler is falling apart too as of lately, any chance its the cause?

i have noticed when i first start it up in the morning, ice cold start, it will start, then the idle will rise and fall for no reason, im not doing it, not sure if that's related, as i never noticed it doing it before. it would normally go up to 800 or so rpm till warmed up, and it only does this jump one time when i start it.

no cel lights at all. but at a idle im hearing what may be a misfire, but not sure because of the muffler. but the engine will jump every now and then. its nothing regular.
