First guess, dirty / sticking / jammed idle control valve.

It's mounted to the bottom of the throttle body, with a couple of small water hoses & a vacuum hose going into it.

Take the throttle body off the plenum disconnecting the inlet pipe, throttle cable, wiring plugs & hoses mentioned above, then undo the 4 very tight screws holding the idle control valve to the throttle body.

You'll then be able to see inside it & clean out whatever is jamming it.

Many Thanks, I'll get a look at it in the next few days and report back

we have the same problem, i the forum seemed to suggest injectors but i have just seen in two other forums it could be a 02 sensor.

I have had this problem on first start in morning and threatening to stall. Toyota looked at it and said the disributor cap and rotor arm were 'pitted' and replaced them . It is a bit better now but I did also put STP in a full tank of fuel and so as yet cant say which has improved the car??
