95LT188ChevyTruck

Well I have had my LT1 installed in my chevy truck for about 2 years now. It has been nothing but smooth sailing until now!! haha. I don't kno wats wrong with it and I need to drive my truck tonight to pick up a scooter uh oh. Well here is wat it does, it idles high then low and backfires and eventually stalls. Maybe I could get like a sound clip of it or something and that might help but if anyone has had the same problem please help!! it would greatly appreciated!

I hate to always point the finger at the opti, but it sounds like the opti.
