This is the situation:

98 Contour Sport. Regular oil checks. Just replaced spark plugs and air filters.

It idles a little erratically (750 drops to 500 then back), and has started hiccuping/hesitating/pausing/stuttering on the acceleration (either at a light or entering a highway). It runs well at a constant speed but is still troubling.

From everything I've researched, I'm of the mind that it might be clogged/dirty spark plug wires or the ignition coil. Otherwise, perhaps a fuel filter and/or pump.

Any other suggestions? If I did the wires and coil myself, any idea how long and expensive it would be (I'm in Canada).

Thanks... and this is my first posting... just joined.

My car does the exact thing sometimes. Not all that often, and I haven't gotten around to seeing what it it. Of course it might be different in your case because you might have a v6 where I have a 4 banger.
