So I have a 2003 expedition 5.4l that has the intermittent problem while driving in high temps. (sometimes throws the cylinder misfire code) and I was reading the TSBs on ALLDATA...
It says specifically to NOT change the coils and plugs but rather to update the computer to a certain release... Im curious if anyone out there knows anything about this or has done it... did it correct the problem?
I am probably going to go ahead and change the cops and the plugs anyways as I am at about 180,000 miles. Im just curious to know if after doing so will it be safe to send my daughter over the mountain (about 100 miles) or if it will still be plagued with the same issue.
thanks in advance!
