EL 6 cyl rough idle


A little while ago I posted about my head gasket probs with my 96 EL 6 cyl. Well anyway the repair job on the head gasket seems to have done its trick and I've not lost any coolant after doing about 2500 kms on it. But one problem still persists - it still idles a little rough, more so when in drive. The head gasket had a slight leak for about 6 months or so then slowly got worse, and about 3 months into the problem the idle started to go from being ultra-smooth to rough and apparently misfiring. I figured the problem was the result of the head gasket leaking and was expecting it to go away when repaired but it hasn't helped much.

Basically when idling it vibrates quite a lot and you can feel an irregular 'kick' - it feels like a misfire. Its not so bad that it stalls (thankfully) and the tacho doesn't move much if at all but its not the same since the head gasket. Any ideas? I've done the plugs, leads, cap, and rotor. I've searched a bit on here and come across a few people saying it was their camshaft but wouldn't that affect it across the entire rev range?

If someone could shed some light on this annoying problem that'd be great.

Re: EL 6 cyl rough idle

Check the inlet manifold gasket for leaks. If thats ok try another coil.

Re: EL 6 cyl rough idle

Even before coil,
grab a multimeter and check the leads. Genuine motorcraft leads have served me well, but eh aftermarkets tend to fail readily.
