Engine Performance problem
2003 Chevy Truck V8 Four Wheel Drive Automatic 73000 miles
My 2003 Chevy 1500HD has a 6.0L in it that feels like it's "pulling hard" all the time. At 60mph it may need to downshift just to climb a hill. Pulling my boat this all gets much worse. Fuel mileage is down, around 6mpg in town and 10mpg highway. Also with cold morning starts I will sometimes get multi-cylinder misfire codes. No body seems to have any idea why including the dealer. They did the recomended throttle body cleaning and sent me on my way. I would be greatful for any advice.
have the same problem?
