I tried to search for this problem here but came up empty. I have been getting a CEL Only in the wintertime. Using the Auto Ingenuity Enhanced Ford Program
I get codes for Lean fuel on both banks.
Using the Ford Factory Service manual, I started troubleshooting per the fault tree. Every thing checked out till I got to the MAF sensor. Using the live info screen All readings look good except the Baro Pressure. It's only reading 13.1
PSI when it should be around 30 psi. The Baro Hrz. reading is what it should be, but is in Yellow because of the goofy Psi reading I guess.
I put A new MAF sensor in With the same results. Even disconnected the pressure reading are the same. is there a separate Baro sensor on a 99 4.0
SOVC ? I thought it was part of the MAF.
