I have a 2006 Dodge Durango 175,000 miles I had a fuel pump put in Feb of this year, but now I am burning a lot of gas. I have to fill up my truck every four days now. Before I could ride on a full tank of gas for a week and a half. My mechanic put it on the computer and it found nothing wrong. He suggest I get a complete fuel injection cleaning kit. I did but I am still burning a lot of gas. Does anybody know what is happening? Can you tell me what the problem could be?
