06 f150 5.4 code help
SO my truck just started running rough till it gets fully warmed up. 136 k miles, just did a plug change this spring. It felt like a misfire, but took it to advance to pull the codes.
I was told the following came up.
htd catalyst
sec air sys
a/c refrig mon
egr/vlt sys mon
I'm pretty handy under the hood, but where should I start first. The AC is the last of my worries now.
