I read your posts at Gassavers.org
I would wager the EGR is loose at the gasket after numerous attempts to remove it have failed.
There are 2 holes that the EGR covers and regulates and the gasket seals between them , if there is a leak either between the 2 holes or outside of the gasket it will give you a horrible random bucking.
I would do what ever it takes to get the EGR removed and minimum use high heat RTV to reseal the gasket.
My VX has never had the bucking issue but I had a '79 Ford Fairmont 302 that had the exact same issue, solved the way I described.
Hope it helps.
