I had my fuel injectors replaced on a recall and now my mpg has dropped big time WHY???
they could have installed a bigger injector,if disatifed take back to dealer and complain,gas is to high to be loosing MPG.could be they have not sealed or seated in yet.
you should look at the oxygen sensor even if you have bigger or smaller injectors the time they fire is set by the oxy sensor and computer.also if you unhook the battery for a bit then hook it up will reset the computer functions and cause car to re learn factory settings
