Thanks for the reply Arthur. I agree with you and it would not be the first wrong diagnosis from this dealer. Dealer stated that when they pulled the cam advance plug that the issue went away.

If pulling the cam advance plug makes the problem go away, what is your thoughts on the trouble? Something I did notice when I happen to be outside the car and the engine was on the Verge of dying, is the engine was making a lot of noise. Like it was back firing through the intake but not the exhaust.
