1999 land rover discovery runs hot at idle and runs rough and hard starting

What is your question?

I replace the fan clutch,coolant bottle and 1 a/c fan. It always run good while moving but once you sit in traffic or stop at a store and turn off the engine and come back to restart it. That's when it's hard starting and rough idle until i rev the engine for about a minute. I've done a full tune up except the fuel filter about a year ago. As long as it's moving it's fine until i idle
