I have an 06 F250 That will die out at times when I put it in Reverese, Dealership has it and it has not done it for them. Seems to happen when truck is warn and does not happen all the time. Has this happened to anyone elese and if so what was the cause.

try putting a new pvc valve in it.i had an '86 that did this and changed the pvc valve and it fixed it.
