Thank you for your reply. I think I have solved the problem but would like to know your opinion. The rubber air hose that connects from the air box to a plastic fitting next to the fan/shroud had become disconnected. I reattached the larger (4-5") rubber hose to the plastic fitting so the sensor is not getting hot engine compartment air. I believe with the hose not properly attached, the air box was pulling in the higher temp engine compartment air and adjusting the mixture accordingly. Do you believe I am correct? The car is running fine now! Should I continue to investigate? A little history on the maintnance, I had kept the car properly maintained wiith 168K miles. The care does not burn a drop of oil and is mechanically sound. Thanks for your reply.
