Engine idle problem HELP
I am having problems with my RX300, year 2000. Engine Idles at about 1 then jumps to amost 2 and back down to 1 every 7 seconds. I tried changing idle air control valve / catalyc converter / 02 sensors. But that did not solve problem. Did this happen to any one else and what was the fix. Please help

Do you have any CEL's? Rather than throw parts at it, let's try to get down to the source of the problem.
I suppose you cleaned the throttle body while you were in there? Did you unplug the battery to reset the ECU?
Does this happen on a cold idle? Or, will it happen after the car is warmed up as well?
Any vacuum leaks?

Edit: You should be able to remove the 2 screws that hold the black "bake-a-lite" (sp?) piece that contains the magnetic fields and actually run it and turn that little round piece on the end of the air intake vane and see what you can do with the idle. See if it turns free and if you can simulate the same idle fluctuations that it does with that on. You don't have to take anything else apart to do that. You should even be able to take the screws out and turn the part with it still on and connected. There is a small adjustment available with the screws in, but with them out, you should be able to turn it unlimited, to see if that makes any difference.
