Now I think the (check engine)light is flashing 3 times which appears is the air intake sensor so im going to tear into it again tonight......would that somehow cause the engine to backfire when running?...thanks
What do you mean by "an air leak"? I have the same issue with my fusion. Some days it will blink all day once the sled is warmed up good. Other days it will come on only a few times then disappear.
