Have you pulled out the spark plugs to see if there are any tell tale signs on them.They are a good indicator of many problems that occur and can save a lot of time isolating the problem.They should all be the same colour.Is the air box and lid properly secured with no leaks or splits in the intake tube.Have you put injector cleaner in the fuel tank to clear up any possible dirty injectors.Therse a few things your problem could be including engine vacuum leak which you can find by lightly spraying carburettor cleaner around suspect places such as inlet manifold and around injector seals.

SOURCE: rough idle

Have you had the throttle valve cleaned?

Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: will idle high sometimes up to 3000 rpms when driving or sitting still

I have the same Jeep and same problem. The engine was running rough. The Jeep dealer fixed a vacum problem in the manifold and they then decarbonized and cleaned the fuel injectors. After these repairs the idle problem began, it would spike to 2000 rpm while sitting at idle, sometimes it would slowly come down, sometimes I would have to tap the accelerator. I took it back in and they then replaced the throttle motor and reprogrammed the PCM (Power Control Module?) Still same problem. Now they suspect a another vacuum leak and I am taking it back in on Tuesday, will let you know what happens, $ 1,300 so far.

1989 toyota camry idles too fast


You either have a vacuum leak or the Idle Air Control Valve (IAC) has become dirty and stuck. Read this

http://www.justanswer.com/toyota/1ktck-92-93-toyota-camry-fast-idle-turn-down-oem.html

One other possibility for a high idle if you have A/C fitted is that the A/C idle-up valve has failed in the high-idle state. If this needs testing, do so when it is hot.

R u start the car in cold morning or any cold condition? If so, it is normal revs up itself. Sometimes I see some cars revs up to 2000 rpm for 2 to 5 mins, then drop down to 1000 rpm.

High rev at cold (winter cold!) idle


Your toyota technician should know what a "cold starting solenoid" is. It is the little thing that works your throttle until the motor warms up and something else takes over. I'd suggest going to another technician.
