my 91 camaro rs with a 305 is smoking, and popping out the exhaust, any help?

go to an autozone and ask if they have a tbi or tpi cleaning kit if they do buy and follow the directions that should fix the problem

that could be a number of problems, does it idle? will it not rev? ...

When our Camaro did that, it turned out that the rad was shot and it needed to be replaced. :( But if you have a good mechanic friend, it shouldn't be too costly to replace. :)

But like everyone else said, it could be something else, so it's a good idea to have it checked out anyway.
