How to unplug injectors on V8?
I am going to replace the EGR valve and all intake gaskets on my 2001 740iL, but cannot for the life of me figure out how to get the retainer clips on the injector plugs released to "fold back" the wiring boxes as shown in the service information. I can barely see one end of most of the clips. The plugs will not release because of the clips, and darned if I see any way to get to them to release them. I cannot fathom that the clips are even there since the box containing the plugs is restrained by fasteners! If I ever get them off, the clips will be removed completely.
I have had a chronic "mixture control off idle, cyls 1-4" for some time, but have not been able to resolve it. Recently though I have replaced one coil, and new plugs, but am now having slightly rough idle, and a little grey smoke on startup. I suspect the EGR valve, but any other ideas?
