got a 2004 grandcaravan , 45,000 miles. The other day it started running rough on engine idle start up and the check engine light came on . I got the light to re set turning the inigiton key 3 times on and off, the van still runs good down the road, any suggestion what is g0ing on? Does this sound like fuel filter problems? the van has the 3.8 v-6 in it.
