I have a fully rebuilt gen 1 coyote in my fox. Everything was new upon assembly.
Once car was together I had it tuned, at that time we noticed bank two exhaust phaser wasn’t keeping up with the bank one exhaust phaser.
I took it home and replaced both phasers on bank two and all has been good. Last summer car ran perfect without any issues (from motor).
This year car has been doing great up until the weekend before last when it sounded like it was missing. I went through and found that bank two exhaust phaser is not following bank 1 again... I tried new solenoids but did not help.
Can someone shed some light onto why I’m going through bank two exhaust phasers so frequently? Shouldn’t they last more than 3k miles?
