Fuel Mileage Went Down

[ChrisA]

Hi Guys,

First time posting, question is: After replacing all four injectors what could have caused my fuel mileage to go way down. Like 180 miles on a full tank. Used to get around 300 in normal city driving.

Thanks in advance.

1)wrong injectors2) craked one installing it3)disturbing another connector like the coolant temp sensor connector during your install.4) a fuel leak from the hoses attached to the fuel rail.

Or you wrecked an o-ring or two installing the injectors. Make sure to use some lubricant on the injectors o-rings when putting them in.
