Re: Strange P0300 occurrence
The furnace is fixed and the car is running great. We've been making it a point to drive it whenever possible. Have driven it over 110 miles now with no issues. Let's call this one solved.

Re: Strange P0300 occurrence
One more post then I'm done with this car today. New wires did little to help. I did a resistance check on them and they were within specs but I figured 14 year old wires should be changed.
