I have a 2004 Bravada, which I really enjoy, but is anybody getting 20mpg on the highway? Any ideas for better mileage? I already have a K&N filter. Best I've gotten is 18.9mpg at a steady 76mph.
Also, any ideas on low to mid range accleration lag? Have to pump it up a bit to get it to respond, although it is a quiet, heavy vehicle.
Thanks for any thoughts. |

| Has a standard tune-up been considered? It may help, or even cure all the problems you listed. (unless of course it has been done) |

| It only has 41000 miles, and runs very well otherwise. |

| do you have it in 4wd mode on the highway? or 2wd? your mileage is also dependent on the gearing, tire sizes and so on........ You might want to get your vehicle scanned so you can look at your A/f ratio it could also be a oxygen sensor on its way out causing your crappy mileage |
