When replacing fuel injectors, do you have to use all the same brand? I have a 3.1 L. I had one injector replace a few months ago and the other 5 recently. I know that I used different injectors(Borg Warner) than the one my mechanic used(ACDELCO). Since replacing the 5, now the car is harder to start than before. Could the different injectors be the cause?
Any help is greatly appreciated!
