Engine Performance problem
2003 Dodge Dakota V8 Four Wheel Drive Automatic 37870 miles
After 30K maintenance service, mileage dropped from 17-24 MPG to 10-11 MPG. Every few weeks I get a MIL check light (steady) with a P0441 code. But by the time I bring in to dealer the light has gone out. Dealer mechanic checks sensors and hoses and lines and runs NVLD test, no problems. No gas seen in evap lines, inspected hoses look okay, no vacuum leaks. So nothing gets fixed. In a few days or weeks the MIL light will come on again. Otherwise, the engine starts and runs fine, only the fuel economy remains abysmal.
