SOHC bogging
2000 Explorer SOHC, Has come down with a case of the boggs when you try to take off from a light. No power feels like a 6000 pound trailer behind me. There are no codes and I have gone front to back looking for the problem and found nun. I have a SCT chip and have turned it off and the problem is still there. Changed gas and have run 100+ oct. in the X no change. Runs fine when above 35 mph.

Well the trans. is good. everything working like it should. The maf could be, but it should set a code of some sort I think. I could be over thinking the problem too. LOL

Well, with that ruled out and thinking EGR, I have to wonder if the EGR is opening too soon and too much. Remember, the EGR is closed at idle; if it opens too much too soon it will boog/surge. I'd like to think this would trip a code but I suppose it's possible that if there's a partial malfunction it may not. I'd be tempted to temporarily remove/plug the vac hose to the EGR valve and take a drive. If the problem goes away, you're onto something.
