In the process of repairing a leak, one of the injectors was damaged. Since that one needs replacing, should all the injectors be replaced at the same time? The car has 240K miles and AFAIK the fuel injectors have never been replaced. I'm on a budget as far as this car is concerned, but would like to do the job right. I'm considering just replacing the one injector with a similar part from the wrecking yard, unless convinced it will be worthwhile to put all new parts in. Thanks in advance for any advice.
