If you checked as suggested for vaccum leaks and have no improvement or only little... Assuming here its KE-Jetronics fuel injection.... on the excellerator linkage is a microswitch that gets activated when the excellerator hits idle position (decel fuel shutoff)... it has an influence on your idle quality, also the electronic component in your air/fuel mixture body (Airflow potentiometer) could be the 'guilty' party aswell as your Idle valve (on single belt engines) that is stuck between the inlet pipe of number 3 and number 4.
Anyway i hope this helps to locate the problem
Hi the bad starting is most probably caused by the big breather pipe under the inlet manifold towards the rear it's about 25 mmdia but hard to find if is a bad fit it alows air to be drawn in and will cause bad starting if it comes off .as mine did engine will not start at all when you put it back put a cable tie on it chris

Re: Engine warms up and idles at 2000RPM
Sounds serious if all those people were not able to solve the problem
after having the car for six weeks and getting toyota tech support
Since there are no trouble codes and all those parts were tried I'm a
little bit stumped here also, almost all engine malfunctions will
trigger a trouble code to turn the check engine light on.
Can you tell me a little history, did you buy the car new, how long ago
did this start, was the car in an accident, what recent repair attempts
were made to correct this problem, if any other than swapping the
There is one other possibility that will not trigger a check engine
light and that is that the fuel may be contaminated, have the fuel
drained and put in fresh fuel in the tank to see if it solves the
problem, any input you may have may help me to solve this.

CarGurusApr 2, 2012 - As I continue to drive, the RPM needed to keep the oil light off (and therefore ... and when the light does turn on, I'm either at the other end of town from ... let it idle for 15min with the dummy light flashing? does the engine start ...
All the above is normal , except 2000rpm is a little high at idle . can be adjusted down to 1500rpm. the computer adjusts the engine speed . in drive the transmission loads up the engine idle drops to 1000rpm . in park engine unloaded rpm increase all normal.
Could be a defect in the ECU. But 1000rpm is not that high my cars normal is 1000rpm. but some older models were about 700rpm
The AC rise is normal. You may want to have a OBD II check by your garage or you can buy a unit to do this. It will scan the sensors fitted for any problems.
The PCM (power control Unit) controls the idle speed base in input from various sensors, one of them it's the coolant temp sensor, this sensor may be telling the computer that the engine it''s too cold and the computer will keep the idle up to help the engine warm up faster
with your a/c issue, the compressor might be faulty and not engaging and disengaging. have the a/c system level checked and recharged if necessary...if okay, then start to check the clutch in the compressor to see if it kicking it or not...maybe the low side or high side switch...as for your idle, it really didn't sound like a distributor,.....to me it sounds like you have a faulty, Idle Air Control Motor in the throttle body allowing in too little air, and when a/c is on, its just right...have them both checked,
On most newer cars there is a fast idle motor controlled by the computer that will hold the fast idle till the engine reaches a preset temp in the computer then the engine should drop down to the set idle according to specs for that car. If the oil pressure continues to stay low after the idle goes down you may need to replace the oil pressure sending unit or if worse case the oil pump.
I have a similar problem which seems to stop ,if after 20 mins of driving or warmed up engine if you stop for 10 mins the revs die to a more normal 1500 revs! it is a spanish car now living in theUK I think the problem is choke related.
