Monday I replaced the #5 injector because it had died. I replaced it with a brand new stock injector, and a new injector control harness. Prior to the injector dieing I was getting decent fuel mileage. On my 19 gallon tank if I filled it I could get 85-90 miles out of a quarter. But now ever since the new injector it seems like the truck is drinking fuel, I filled up after I replaced the injector on the 19 gallon tank so far have lightly driven 103 miles and its just before a half
what is going on? would the new injector cause this?
