One diagnostic saying Intake manifold, the other saying EGR valve and manifold?

What is your question?

I got a diagnostic done over a year ago and one is showing a code for intake manifold and a different diagnostic is saying manifold and EGR valve. The car uses way to much gas and misfires and some times sounds as if it will stop. I recently went to a tune in and tune up event and they said my gases from the tale pipe are clean, so I'm totally confused.I got new radiator system hoses put in along with a new radiator fluid compartment ( not sure if that's the right term) but the coolant leaks into my front right tire rim, what's really going on with my 2004 Ford freestar?

What makes this problem better or worse?

Not sure

How long has your 1994 Volvo 940 had this problem?

12 months
