Bad Coil
Hi, im new to the forum. I really need the help of this forum. I have a 2004 Nav, and I have been to the dealer and 3 other auto places, were my Nav was put on a machine. Out of the 4 , none of them can find any codes, or whats causing my rough idle. For months, I thought it was bad gas, so I started using Chevron and Shell, no help. Yesterday, I put the truck on what they say is a 15k computer. The computer couldn't pick up any thing, but the service tech says he knows a coil is is missing. I said lets fix it, he said he would have to check every single one of them, wich would be pricey. He also said to drive it until it gives you a code, then we can pin point the coil. My question is there any other way to find this bad coil, im not comfortable driving my truck like this. Plz HELP!!!!

I have seen a few Fords that the missfire monitors were shut down . A Rep told me it happend sometimes with problem vehicles . They would NEVER set a missfire code or turn on the CEL . You may have one of these . A good shop will still have ways of finding the miss . Using a scope on each coil , A pressure transducer in the tail pipe and the proper scope software , and a few other tricks . Good luck !
