Limp mode with no lights or codes.
Wow do I have a problem. One day as I was driving
my explorer home it suddenly had rpm going up but
the mph going down from 40 to about 20. No o/d
no check engine light, no codes. Researched and
figured it was in limp mode but I don’t know the
cause and don’t wanna throw money and it. I
recently replace to egr valve about a month ago but
I just lost and need help!
