My car had a really bad miss when it was idling, we replaced the spark plugs and wires and the miss is gone but now after starting the car, if i do not keep my foot on the gas the car dies, any suggestions?

Clean the idle air bypass with some spray cleaner while fast idling. The TPS sensor wearing out, dirty fuel injectors, & the EGR valve stuck slightly open st idle can all also do this.
