The light used to come on and stay on, then it was every now and then, and now it rarely comes on at all. The first time I noticed the check engine light on, the whole car started rumbling like there was an exhaust manifold leak or something. It was really loud too. But that went away on its own, Thank God.
How much did it cost you to replace the crankshaft positioning sensor? Was it an easy fix? I'm thinking its either the coil pack, spark plugs, or some sensor. Can't be the air filter or fuel filter, I changed that recently.
A couple years ago when I had problems like this it turned out to be the o2 sensor.
