hello, i have a 2010 journey with 160000 mi. the other day i was driving and it stared to misfire and the check engine light started to flash.went to the part store and had the code pulled and it was the crank sensor code and a misfire code. changed the sensor and gave it a test drive and it was still doing the same thing. put another sensor in and changed the spark plugs. test driven again and still not running right.idles ok start to drive in a couple hundred feet it starts to misfire when you turn the car off and restart it run ok for a couple 100 ft then the same thing happens,
any thoughts im at a loss
