I have a 2003 Frontier crew-cab, V-6, with 57,000 miles on it. I bought the car from the dealer with 10,000 miles on it and never had to make any repairs beyond changing the oil and replacing air filters as needed. Then in June of this year, the AC went out. I took it in and was told it was leaking coolant, and we got it repaired. Prior to this, my truck got good gas mileage of about 17 mpg, freeway or city driving. Since repairing the AC, the truck has been getting about 14mpg, and freeway driving definitely gets better gas mileage than city driving. I should also add that since repairing the AC, if I have to sit idle for long periods of time, the AC will start blowing warm air and it did NOT do that before. I took the truck back to the garage in August (I had a baby the latter part of June so the truck did not get driven much during that time), who could not replicate the air turning warm during idle. As for the gas mileage, they suggested a fuel system flush, replace the air filter, spark plugs, distributor, etc, (a basic tune-up), an AC service, fuel injector service-we did all of this, plus got a new battery. The truck does run more smoothly than it was but the gas mileage has not improved. This is killing me, I am losing about 50 miles per tank of gas which is a round trip from home to work! ANY help you can give is appreciated!
have the same problem?
