Engine Cooling problem
1996 Chevy Lumina 6 cyl Two Wheel Drive Automatic 195000 miles
Can a bad intake gasket cause EGR code/problems? I have replaced EGR valve (with another used one that I cleaned from junkyard), have cleaned inside intake. I am pretty sure my intake manifold gasket needs replacing, could this cause problems with my EGR? I am getting terrible gas mileage.
