yea..i get really bad fuel economy. lookin at 20-25 mpg. i know i drive at about 75-80 on the freeway, but i didnt think that it would reduce my mpg by that much..plus i see that it goes down alot when im driving regularly..
just maybe running to rich..maybe reset ecu? but main question is how do you know if your o2 sensor is bad. thanks guys! x --------------------  Pandelica 2.0 in progress. |
