P0688 & random shut off
My 07 Rango 4.7 Limited FLex Fuel keeps shutting off randomly. While driving as well as idling. I have to pull over, take key completely out, than restart it. Always restarts(but i have to remove key i cant just turn it). i am to nervous to drive it. I took to the dealership. They kept for 2 weeks. Claim its the main harness to injectors/coil that is faulty. Quoted me $3,000 to repair. insane right? After bringing it back home i checked the whole harness and found that it has no splices as they claimed. As well as 80% of the harness wasn't even messed with. i think they gave me an outrageous quote knowing i would say no, so they could be done with it. I have read everything on the internet for this issue and have yet to come up with a fix. engine was rebuilt 1 yr ago, pretty much ever sensor in car is new. issue started a couple months back.
