2005 explorer
I'm stumped I have a 2005 explorer 4.0 flex fuel but as far a I know only ever been run on gas . The truck had a bad misfire at idle and sometimes it won't go once you put it in gear if you wait a little it will finally start revving up and it drives alright besides motor jumping around at idle here's the kicker no codes I did get a random misfire code a couple of times during working on the truck but hadn't come back changed plugs wires and coil new cam sensor fuel trims are right in line tested o2 sensors all are working correctly pulled sensors checked back pressure all good less than 1 psi cleaned throtall body for kicks no change cleaned maf no change don't know what could be making it run so bad and misfire but not effect fuel trims any ideas would be greatly appreciated
 






Take the vehicle and get the ECM updated.
