a little wrench appeared on my dash.... truck went to an idle , would not go!!! looked it up in the manual ......ETC???? shut the truck off ... started back up no problems for about a day... then while driving same thing car went to an idle position and now my engine light is on... it seems to be running fine , but just curious on what i need to do... is it something major...can i fix it or do i need to get it to the dealer???? thanks for any help

 

probably would need a code reader to find out what is causing the "light" to come on - it may or may not be a big deal. Mine came on one day, so I brought it in to the Ford dealer, they hooked it up and found out that my 4x4 solenoid was bad. I bought the part and changed it in about 3 min. - been running fine every since.

 

If your truck is an 04 this might help you. https://www.ford-trucks.com/tsb/full...hp?tsb=05-14-4


If still under warranty take it to your dealer.
