I've got these 4 codes on my 05 4.0 that have been up for a little while now. I have only tried replacing the gas cap which didn't solve the issue.
I'm guessing these 4 codes are all in relation to one another. Do they ring a bell for anyone? I was planning on going to the mechanic and getting a smoke test done but anything else I should check prior?
Thanks
