99 ford f150 5.4l issues
Hello,
I'm new to this type of thing but I'm lost I have a 99 ford f150 4x4 with the 5.4l 2 valve. It started throwing codes p0171 and p0174 checked all vacuum lines and found a hose off replaced it and now it seems to be getting worse.
It now is has codes p1131 p0136 p1151. Checked everything again tonight when I got home and noticed that the egr tube was not hot does this mean that the egr valve is stuck open. Any help or ideas would be appreciated.
Thanks
