My 2006 CRD has lost an average of 3 mpg during the last 3 or 4 fill ups. I have not changed my driving habits. I haven't checked the air pressure on the tires, but the sensor bulb hasn't come on. Any suggestions? :cry:

Have you cleaned your MAP sensor?

Check your air filter as well.

Check air filter, check tire pressure, clean MAP. How many miles are on your current fuel filter?
