A few weeks ago I was sitting at a stop light, and the revs dropped pretty low, car started shaking slightly, and it sounded like it was knocking pretty bad. (Running with great gas, tried many different gas stations since then, not the issue :/) I noticed the check engine light came on, so I went over to Auto Zone and the code came back to a camshaft position sensor fault (p0340). I did a bit of searching around the net and came to a conclusion that it MUST be the alternator. So...I yanked that bugger out of the car and took it to be bench tested at Auto Zone. Surprise surprise, the alternator checked out ABSOLUTELY FINE!! I did a bit more searching around the net to no avail, so any of you guys familiar with the issue or have any ideas?? Btw--I've been looking around StangNet for forever, and I finally decided to join because of this issue, so, hi everybody!
