You revel in solving your first Big problem and saving yourself about $1000 in diagnostics Labour and parts that a tech would have thrown at the car. We are proud of you here,too.

The real masters on this board...we have maybe four or five of them on this Board .....will play Car Soduku in about 60:seconds.

I wonder if I could ask another question, though not related. Retirement for me has lead to a sharp drop in my driving-now about 3000-4000 miles per year. So it takes 2.5 to 3 years to get to an oil change interval of 10000 miles. What should determine the frequency of oil changes-mileage or time? ...
