Hi, my name is Al and I just signed up on the forum. I have a 2007 F150 King Ranch with a 5.4 liter Triton. I am here looking for some answers to a nagging problem. I love the truck but have some maintenance questions that I can't seem to get answers to. I suspect that I will have to post to a "maintenance section" here to start a thread but being new to the forum I thought it best to start here.
