E250 ford van suddenly started blowing hoses off that go to the egr position valve sensor. Even when both hoses are on the 5.4L engine has no power. It will take off ok as long as I take off slowly....


Most likely the catalitic converter is restricted causing excessive exhaust back pressure which blows the hoses off and causes the no power issue
