Will any damage be done if I only replace one side of injectors? Its not the way I like to operate but money is tight and want to make sure I wont be doing more damage than good by replacing one side. Any info would be greatly appreciated

 

Unless the other side is dumping fuel into a cylinder then no.

Plenty of people have done it this way.

If you want to do it this way you might be better off replacing only the bad injectors. Do a balance rate check and a fuel return test to find the problematic ones. This way you won't have to replace all eight.

 

it is a lot of labor to swap another one later especially if it is on the harder side. I see people put a new set in the side that is more difficult, then test the remainders and put ones that are still good on the side that is easier to install.
