I posted a couple weeks ago about this--finally got around to checking. Pulled out the plug wires on all 4 cylinders, the idle got worse so you can't say there's a bad plug. Plugs/rotor (which is in tight), cap, wires all replaced within the last year. Wires are Bosch, plugs are also Bosch--have used Bosch before without problems. Wondering if it might be an ignition coil? When it idles, you feel a vibration, you can see the engine vibrating a little bit with the hood open. I did notice a little oil in the distributor cap. I did replace the external distributor o-ring but I believe there's also an internal one. Maybe the distributor is the issue?
