My 2004 jeep grand cherokee overland with a 4.7l v8 ho. Has recently lost a lot of fuel mileage. It started out at 18-20mpg. My wife drove it to ny pulling a trailer when we moved there from kansas. After arriving and unhitching the trailer. The fuel mileage went down to aprox 8-10mpg. Just before leaving for NY. SHe had all of the usual maintenance done. I.E. Oil change, and changing spark plugs. She also had the throttle positioning sensor changed.
have the same problem?
