camaro z28 93

sounds like a bad IAC valve , clean the IAC port if you decide t replace it , look for any loose/broken vacuum lines , spray some carb cleaner down the throttle

Ok I'll try that and let you know if it works thank you

So we put a filter on and added gas to the car it ended up starting but acted like it wanted to stall a bit, we were half a tank when we broke down and the car sat a year with a full tank of gas before we got it fixed.... could this be the reason and also if there is sludge in the tank is there a way to get rid of it...

if the gas is a year old it needs to be removed somehow , you should have mentioned that before
