Thanks for the response, Mark. Yes, when I (finally) had the cause of the
CEL to be on checked, the reader device said the Cam Position Sensor was
faulty and the Catalytic converter was not up to "proper" efficiency.
That's it, just those two problems. I suspect the reason it was on from way
back is the catalytic converter problem. Although not good, I don't believe
such a condition will have caused long term engine problems by continuing to
drive with that particular "fault," just more pollution. Of course I have
no idea how long the cam sensor problem has been logged into the computer's
fault memory, but of the two problems reported, I considered that to be the
fault causing, or contributing to my current knocking and smoking problem,
thus my question. From what I've read it seems a faulty cam position sensor
would not likely cause the knocking and smoking to the degree I am seeing,
faulty though it may be. I just wanted to get some sort of confirmation on
that before I spent the money on a new one and all the trouble to replace
it. Thanks again.
