I have a high idle problem, in park, but when I shift into gear it settles down pefectly. Happened the other night after a particularly royal caning, testing out brakes and things.

Also does anyone know what the second plug goes to that comes off the AFM...?? THE AFM is the big plug and the little one is swinging in the breeze..

I know this might be an obvious question but have you got the aircon switched on?

There is no aircon on my motor. Maybe I should check the aircon wiring, to make sure it is all completely de-activated.

Oh yeah, im getting post ignition, after I switch off it stays running for a around 5-10 seconds...

It feels to me like its overfuelling, which is helping it run-on, will check air filter and intake plumbing.

It makes sense too, because it is getting up to 89C much faster than usual.

I have a full aftermarket alloy radiator, and a digital temperature monitor. It never used to get this high, or get this hot this quickly.

Does anyone know if changing the length of the pipe for the Idle control valve will affect the function of this device?

Robert I think you need to clean the throttle body around the butterfly. it will cause your revs to alter and cause run on ,use a carb cleaner and toothbrush .good luck

Hey mate, the ICV was working fine until I changed the intake from the standard one with that big box into a polished stainless one which goes over the back of the motor to new airbox.

It actually does look to have a little corrosion in there... but the butterfly is opening and closing quite freely it would seem.

Okay, I tried cleaning the ICV, cleaning the intake plenum, and intake butterflies. They are fully functioning :-(

I have a series of problems:
Catalytic converter light on (not previously a problem, no cats, and not the cat wiring)

Coolant temp seems to be much higher than what it used to be and temp rises much faster than it used to.

Alternator not charging warning in Japanese, when alternator is actually charging and PS pump is not leaking and alt. is working fine.

I have the idle at 1100, after adjusting the cable from the cruise control. (Still high idle, although not 1500 anymore.)

Interesting, normally cat light and alternator warning is the classic indication that the P/S pump is leaking.

Try ECU reset or check for any Vacuum leaks and check the TPS as well

Okay checked TPS, reset ECU, and no longer have the Catalytic converter light? WTF?? Double checking vacuum leaks and there is none, I even wenty back to the entire original air intakes.... No change to the 1000-1100 idle.

Could one of the sensors in the output housing of the gearbox have anything to do with a high idle?
That gear spinning one is a zero speed sensor right? Maybe it thinks its in gear, because in gear the problem disappears????????????

I even tried running the original hose length back into the ICV because a Toyota mechanic suggested too, but that didn't change it.

Maybe if I hang a big turbo off it, it will use the extra fuel, and it'll be happy days. LOL...

Okay, I pulled and checked all fuses and went back over the wiring harness around the main fuse box. No change.....and I took it for a short drive and its all settled back to normal...

Cold start issue?

Seems to come good over 70 degrees???

I can now say that it is most likely a cold start issue coupled with the cruise control, somehow...

Disconnected cruise control and everytime it gets above 70-72 Celsius, it drops down to the 600ish mark for idle..
