Car starts easily, but will not idle without constant pumping on gas peddle for 10 to 15 minutes until engine is warm. Then it runs/idles fine. Due to all this pumping, car starts smoking from (I think) exhaust near rear of engine. I cant take it to a mechanic because of this condition. Hope you can recommend a solution with a part I can access & replace?

Clean out the idle air control valve, EGR valve and test the throttle position and manifold absolute pressure sensor also the coolant temperature sensor-
