I have a 1995 Chevy Blazer and when i stop at a red light it seems to idle

high on its on? idk its been doing it for a while now and its just getting worse and worse every time its like its wanting to cut off like theres no gas when i know there is gas in there ive tried injection fluid and everything and nothing seems to help at all and when i crank it up or turn it off its like smells like gas really bad and i just don't know what to do anymore

It sounds like a leaky fuel line, or possibly the fuel pump, or fuel filter. The filter would be the easiest & cheapest to fix, while hope it's not the pump, for that can be quite difficult to fix & not so cheap.
Good luck! Btw, personally, I think Chevy's the best! &, furthermore, would like to find a Blazer for myself.
