Backfire sounds like gunfire!
my 04z has been sitting awhile do to winter but if there's no sand or salt I will drive it. I only had a half a tank of gas..I did forget to fill the tank. So today I started it up..it fired right up but with a big backfire bang! So I let it run and noticed a slight miss as I gave it alittle gas car is fully warmed up. Then as i turned the car off loud backfire again almost like gun fire lol..no check engine light, plugs wires are new. Can it be water or faulty injector?

So I fixed the exhaust popping which was cylinder 1..started the car no more pop but a ruff idel 2 came back. I hooked up my tech2 and it shows cylinder 3 86 misfires! So I pull the wire out of the sleeve and it's broken in half holding together by 1 tiny wire..how can I not have a check engine light? And what's more messed up is if i have couple of hundred miles on them it would be alot!! These wires are gm reds...but new wires.. problem solved!
