Decrease in gas mileage
I have enjoyed my 2003 Vibe since I bought it new. I was consistently getting 30mpg for years. Now in the last month it has slipped to 25 - 26mpg and that is mostly highway miles.
Any ideas on what is happening?
when was your last tune up,also the gas today is not what it used to be,if running reg,switch to 89 oct.also try a bottle of fuel injection cleaner.
You dont mention your mileage (miles on the car), when a car comes in with this issue I normally recommend a "emmission" service, this is what is included, Flush injectors, remove and clean throttle plate, replace air filter, replace PCV valve, I also recommend a oil change after this service, as well when I am doing the "emission" service I look at the plugs and wires, 90% of the time plugs will need to be done, I also do a scan on the car, maybe a sensor is out, or some thing has gone wrong, Your O2 (oxygen) sensor might also need to be replaced. And I would recommend a new fuel filter. Some customers also have told me that a coolant flush has really helped there mileage. To do all this is a bit pricey (about $400) for your car, but it will run like new again (that price is if there is nothing else wrong, sensor, scan might show something) I know it is alot, and there is alot invloved, but in the end the car always runs great after, A few customers have reported the best milage they ever got after this service, I really hope this helps and best of luck, cheers
