Do I have to plug the egr hole on the lower intake manifold for my sn95? Been searching everywhere and can’t find the Answer
It depends on your manifold. Some Explorer manifolds have internal EGR and some don’t. You need to look at your upper manifold to determine which type you have. I would also look at your PCV system and ensure it is working correctly.I’m using the 97 explorer upper and lower intake manifold. I’m about to pull it off my car as I already put it on. I’m getting oil on my spark plugs and I’m trying to figure this out. The left side smokes under load and at idle it stops.
