Default Manual SC300 idling a little off

UPDATE: 2-15-13
So I checked my spark plugs out and saw a little oil on cyl. #1 and #2 soaked in oil 5-6 with little oil.I didn't get to #3-4 cause of the manifold but,hopefully there not too bad.Car seems to idle/sound a little better? but,I only just drove down the street a couple miles.It idles a tad higher now at 1100-1200 but,maybe it just needs to be driven more to reprogram?I just remembered that my last oil change I added enough oil to hit the"full"line cause winter was coming and I have a small leak coming from the back cam seal so that would have probably explained it.

I have a manual 93' SC300 with 140,xxx miles on it.About a month ago I had a check engine light for for the o2 sensor which fixed the rough idling and really rich smelling fumes.For the last couple days when sitting at a light car has been idling with a light putt,putting sound and a very slight shaking but,the rpm needle stays at 1000rpm idling?I've owned the car for the past 40k miles and I have done lot's of maintenance,new parts etc and encountered many problems but,when is it going to stop I just want a clean smooth luxury ride.Any ideas?

Thanks.

Could be the TPS out of spec...I'd check the resistance on it with an ohmmeter. It should read 0.00, or Infinity. (open circuit) Someone correct me if I'm wrong...you can confirm by going to a thread I made a while back about setting the TPS...
