Engine Performance problem
2005 Chevy Tahoe V8 Four Wheel Drive Automatic 67000 miles
I have a 2005 Chevy tahoe z71. I have noticed a big drop in my fuel economy. The on board computer says that it it only getting about 13 mpg in the city. There has been no loss in power and no warning lights have appeared on the dash. The air filter has also been replaced. I have a friend with appx 100,000 miles on the same vehicle and his says that it is averaging about 19.6 mpg in the city. Any suggestions before I spend big money at the dealership without any answer?
have the same problem?
