I posted on Pelican but thought maybe one of you guys could help?

I've got an '89 with pretty low miles (19k), and have had it for about a year. It drives and idles fine during warm up, after I drive for a half an hour or so, and I pull up to a street light - it settles at a smooth 800rpm idle at first....

But if the light is long, more than say a couple a minutes, it starts to sputter and the idle gets very poor - between 500-700 rpm. It never stalls, but sputters badly. If I give it a little gas it settles out, but then returns immediately to sputtering if the gas is removed. Drives fine afterward when the light changes, then when I pull up to the next light same thing, first ok, then helloooo sputter.

Any ideas on were to start looking?

The plugs are less than a year old, installed by the P.O., I don't think the wires, rotor or diz cap have ever been replaced.
