Default 1990 Corvette

I have a 1990 coupe (81,00 miles) that out of the clear blue started running rough. It almost feels like it's misfiring. When I accelerate, it's prety rough, shaking and loss of power. It's not backfiring or anything like that. I've replaced fuel filter, added fuel injector cleaner, checked all the spark plug wires and vacuum hoses. Any ideas of what to check. It was running great until one day when I was stopped at a light, I felt the engine start to idle rough and then this all started.
Thanks for any help.

I also have a 90. At 80xxx miles I started doing a lot of replacing. It could be a lot of things, most are easy to change (plugs, wires, injectors, filters)
Good Luck, lot of good people to help you here :cheers:
