Recently my wife blew my head gasket. After replacing, putting in a new radiator, and replacing the crank shaft sensor, when I start the jeep, it spudders below 1000 rpm's. I don't believe it is the oxygen sensors. I have to give it gas to start it. The check engine light comes on then will go off. Any suggestions???? Is it my fuel injectors? How do I get my jeep to run smooth again at low rpms? and not stall??  

it sounds like you still have a leak in the gasket or maybe the head is cracked and allowing seepage. you also might check that the head bolts are torqued properly. are you still getting any white smoke or excessive moisture out tail pipe?
