That's great to hear! Literally I'm sure! Haha
Cleaning the uim and probably more importantly the lim on our motors is essential, especially for the smooth operation of the IMRC.
Have you blanked off the EGR? This keeps the manifolds nice and clean.
On mine, the v6 Mondeo, Ford actually deleted the egr system from about June 2000. I think they finally realized it was doing more harm than good!
