Default Camaro NOT RUNNING RIGHT PLEASE HELP

Got one for you guys, I took my camaro out for the first time the other day. I have started it every week over the winter. About two months into the winter I knew something wasn’t right. The throttle didn’t feel as crisp as it did. When you crack the throttle is bogs down just for a second. Anyways I drove it and it idles fine at. And fires right up. Then once it gets hot it has a very I mean very small miss. Only I could tell. But when I am driving and get into it, it backfires through the exhaust? Bad!!!! Then when I shut it off and try to fire it, it takes a couple cranks before she fires? Any ideas, anybody think its bad gas? Any help would be great; I believe it has newer plugs and wires

try taking the icm to your local parts store and have them test it for free

Backfires=check fuel pressure, might be running lean.

I am going with saturation... Wires, cap or rotor.

You could get lucky and have a worn plugs but if you are in that deep, best to do it all right now.

Problems like this will not throw the CEL (Check Engine Light) and a quick inspection should tell the tale.

Edit-

Oh and by the way... That means fixing any leaks while your in there

its possible you have wet gas in it try adding fresh gas and some heet to it.
have the codes checked at autozone or your local parts store.
fuel filter could have went bad.
fuel pump could be dieing
possibly a mouse nest in the air filter.
but my main guess would be to take the car to the parts store and have them scan it for codes. and do a fuel filter. they arent that expensive.

I'd start right there, especially if the car was running OK before you parked it.

I would say that is old bad gas that may have some water in it, try some gas dry or heet like mentioned above, do routine things like change the fuel filter, clean/change the plugs and check wires for wear, burns, cracks etc.. sounds like it may need some fuel injector cleaner too man, start with the easy stuff. its probably just something dumb like this from sitting.

Mine is doing the exact same thing. It's like it misses a few times when you kick it.
