egr and mileage & preformance

[Merv Casteel]

I have 84 town car
think i have narrowed a prob down to a hole burnt in the intake manifold by the EGR system = ford doesn't make the manifolds anymore .
If I disconnect the vac line to the egr - the exhaust noise disappears
My Question --- is mileage etc effected if I leave it with the vac line disconnected and plugged ??????
help - I love the old girl

Egr

Your mileage and power will both improve with the vac line plugged.As long as you don't have a spark knock problem in hot weather, don't worry about it.

Agree. I disconnected egr on ford 460 400 302 and 300 and all ran better with more mileage and power and drivability. Egr is useless. Only gm cars seem to need it.
