Having trouble with my truck either burning a lot of fuel or not reading correctly. I have had a few people say that its not reading properly because its not the right tank, FYI it used to be a 2.8L V6 and now its a 2.,5L 4cyl. So its a bigger tank than what its used to but I'm not quite cnvinced that its the sensor. Need advice or ideas. Thanks . :MJ 1: .
