Car has been idling rough at low RPM but when I get it up to 1,200 rpm or so it smooths right out. Thought it might be dirty injectors so I decided to take them out and give them a clean. Needless to say getting the rails and injectors out was a bitch because they are tucked under the edge of the super charger. I was able to get the retainer clips off and get everything out but is there a trick to putting it all back together? I didn't remove the rails from the car, maybe I should have? Should I put the clips on the injectors first, get them in position and then install the rail? Is it possible to get the rail in place with the injectors already clipped to it? Sorry, bit of a noob here but I don't want to screw this up.
