problem #2

2008Feb 05

Explorer LX 4.0L Flex Fuel

  • Automatic transmission
  • 115,100 miles

I have a 2003 ford explorer and Has a Flex fuel system 4.0L At times not all the time once in awhile I will be going down the road in town and the engine will idle up and down, I think this has something to do with the computer or a sensor for witch the RPM's go nuts Any idea what this could be? It will only do this once in a great while So if it does this again I then take it to a shop they never find a damn thing wrong with it, Does the computer keep track of what is going on if I do take this in ASAP..?

problem #1

(reported on)

Explorer XLT 4.0L V6

  • Automatic transmission
  • 36,000 miles

The Explorer started running rough, would shudder, and eventually turned on the "Service Engine Soon" light. I checked codes and it showed that the engine had a misfire on cylinder #3 as well as a low rpm misfire. Took it to the dealer (Yucca Valley Ford) they charged me for the diagnostic fee and changed the spark pugs (not under warranty). Fast forward 3 months, it begins again, so I pay for new spark plugs again. The service manager I deal with is a great guy, but there seems to be lacking some expertise out on the shop floor.
No change, last time I took the vehicle in, they saw that it had stored a code, but couldn't get the problem to present itself. Still No Change. It is finally due for its 45k service and the problem still exists.
