I got a set of injectors refurbished from cruzinperformance and i wanted to install them today, but I just wanted to make sure it is as easy as the bently book sounds. I took the set out from a car at the junkyard, so it is basically just the same in reverse? Any special procedures and advice? thanks. I have the confidence to do it, just want to make sure it is as easy as it sounds. popping old injectors out and putting new ones in. i dont mess any little things up.
