Re: EL XR6 Rough Idle
I think all manuals are like it. My old manual EF XR6 did exactly as XR6child explained.
I replaced all the injectors, new leads, new plugs and cleaned ICS spotless but it never idled as well as an auto EF 6 pot. Even my manual BA XR6 isn't much better.
It appeared to be more like a missfire, it could be caused by arcing of the plug leads (even if they are new), start the car up at night, pop the bonnet and look for any arcing, especially where the plug leads gather and on the dizzy cap.
