Does'nt like to warm up

99 F150 V6 129,000 miles just bought this truck.Starts up in the morning fine go out after warming up for 15 min.Engine idling low abought to die come to stop light half to two foot it.If I turn it off and restart it,it seems to help and runs ok. Check engine light say misfire number 4 cylinder.Is that the one in the front on the drivers side or passenger Hayes manual confusing me.Could this be an EGR problem?Has anyone had this problem? I'm going to start with the spark plug change first.thanks

Do the plugs. Inspect the old plug from #4 (driver's forward) carefully.

Clean or replace the IAC valve.

Reset the computer (disconnect battery while servicing will do it).
