i need to replace a couple injectors on my 89 gxe and i was wondering witch one i need to order, i ask this because when i went to order them off of carpart.com it there are black and blue ones. i guess i dont really know the diffrence, anything would help thanks.

 

It depends on what number injector needs to be replaced. Blue injector are for the front part of the engine and black are the back side of the engine. This is very confusing as I had mine replaced. And I had black and blue ones. It also could be black at front and blue at rear. Im not that sure. Look down on top of the injectors and see if they have a blue or black dot on them. If you can see the coloured dot that is the injector you need to order. I recommend changing all injectors at once. As new and old injectors don't seem to work to good together. Belive me I know..... Let me know how you go... Hope I was of help.
