loud whistle
Hey folks,
I have a quick question about my exhaust back presure valve. It works fine when the truck is warming up in the morning but when I am driving I hear it come on if I hold the rpm steady. If I speed up or slow down it goes away. Any ideas? Thanks

the EBPR could be sticking. mine was doing it 3 days ago, thought i blew off an IC boot! i turned the truck off and back on and it went away.
i know there's a thread somewhere on how to clean off a sticking EBRP. let me see if i can find it.
