All,
I am having a popping in my exhaust upon deceleration, or btwn gears.
Vehicle in question is a '78 40 w/ stock 2F.
I believe my valve lash to be correct, recently set.
Pulling around 17" vacuum @ idle.
I am fully smogged, w/ air pump. I had heard that my problem may be my air
bypass valve going south. Mine looks original.
I had also heard that Ford had a similar part for cheap. I haven't checked w/
dealer, but SOR is asking $75 for a used ABV...
Anyone know if this diagnosis is correct?
Anyone know the Ford app that will donate the correct ABV?
TIA,
