I've seen from 500 to 1500 RPM in all the manuals I've been through, depending on the year and application (truck/car). In personal experience, 650-800 RPM is acceptable warm operation range. This will also depend on elevation. Will go up to 1200-1500 RPM for cold starting. I live at about 2000ft and my '86 Pickup 22RE idles at 725-750 like a top after about a 3-4 min warm up @ 1250 RPM if it's cold (<45ish).

SOURCE: 1990 toyota 22re high idle and surge between shifting

You have extra air leaking into the intake manifold that mimicks a throttle that is open further than it really is. Check for vacuum leaks.

You have a bad fuel sending unit bracket, on top of your fuel tank. This is a VERY common issue. Frop the tank down, you will see the problem. Replace the bracket, and you will be good to go.

Set the idle


Idle speed or RPM.
old post.
the hot idle on all modern EFI engines
is not set by you ever, it he computer brains job(by EPA laws)
cold idle. is controlled by thermal direct air valves on older EFI.
the Prizm (with a Z) is a Toyota Corolla with sheep skins (GEO)
made same day in the same factory. same parts 99%
a better questions, is tell symptoms first and ask why they happen. 10x better. that.
Idle controls are one of many electronic servo's in the cars ECU/PCM brain, just 1, of many.
read the ASE books on EFI. this is covered there.

Tickover 1500 rpm when warm


idles too fast.
what engine?
what year?

on a gas engine, the idle speed is 100% controlled by PCM at all times. hot.
so its out of control that means the PCM closes the ISC valve.
and RPM will not drop. (its stuck open) or vacuum air leaks
jeeps use speed density EFI system using the MAP sensor.
this means all air leaks on jeeps , cause wild fast idle speeds.
that is all you need to know , to find problem (find leaks)

clean the ISC yet (idle speed control) valve.?

Troubleshooting guide


HOT or COLD engine or both?????????
No year, car, and worse, no engine size stated.
IN GENERAL: works on all Gas cars 1988 to now (EFI)

this is easy, once you know EFI .
EFI does many things, it fuels engine, and creates spark
and 10 other things but on is called, idle controls.
it does this 2 ways, 1 is spare advance (fast) and the other is the ISC. the idle speed control valve. (its just and air valve)
so what did you see. you saw, the ISC SYSTEM (note the word system) is failing
that begs the question.
was humpty pushed , or is humpty bad.
it can be either of both if murphy rears his ugly head.
low RPM
The ECU sees this , (by virtue of the RPM sensors) and tries to
open the ISC valve, if it can the valve is dirty, clean it.
if it can and the valve does open and more air flows, and RPM
dont pick up then, the engine is running lean, or the EGR is stuck open.
I can discover the EGR deal with my right toe.
easy, to raise idle , ISC stuck (clean it)
harder, EGR stuck open.
impossible is gross fueling issues, or worse.

that is how i tell ...
no some exceptions.
if the TPS is not signaling, Im at idle, no idle controls are possible.
or if the ECU/PCM is in LIMPHOME mode, idle controls can be suspeneded.
so not scanning all bad running engines, misses the boat.
i can got to great details but cant due to no year, or engine stated

The year and engine tells me, what fuel controls are used.
some are air density others are speed density systems and
work 100% opposite to each other,,, thus my pause...........

22re starts good but after a minute starts to lopes


surge, lopes, hunts, all same. but does it do this hot/cold or both engine temps.?????????
Im and expert on this.... done many and is related to EFI fuel controls
big time..... (ive even programmed Megasquirts to do this)
first the rules then causes.
Rule 1, The EFI controls idle at all times. so that proves.
Macro reasons.
1: EFI lost control. (stuck ISC?)
2: Engine is missiing (too rich, too lean or never tuned up)
3: or both, usually #2 causes 1 ,

there are ways to solve this riddle
my ways are simple
i test the ISC, see if it works, (unplug it or power it with 12v power supply, ) Id clean the ISC first.

this old car 1992 , scan tools are hard to find for OBD1 cars.
so cant look to see if CLosed loop is working, I can with a scope
but you dont have a scope.
you could put in the diagnostic check jumper and hope for an error code to flash out.
you can look as spark plugs (newones work wonder) and see
if its burning fuel correctly (like old school carb days)
black?> white tips>
all engine carbs and EFI all will surge when lean,.
all, and on EFI it will in fact try to stop the surge,
if lean enough the EFI can actually make the surge worse
is it tries desperately to correct the impossible.@!

that be surge.
i learnd that loping my mule one day.. LOL

How to set idle speed of toyota yaris


no year, no joy (3 generations and 3 base designs)
first off all modern cars there is no idle set.
that ended back in 1988 with carbs. USA, all my posts are for
USA Cars, if you are not USA< then now the time... to say so.
on EFI cars, the idle is controlled by the ECU at all times.
its one of its major hard jobs.
and is the last thing top work right on all EFI cars.

so, to work on any car, the first thing is to
open hood and find out which of 6 engines, it has.

that is first. after checking all fuses)
the 1999 is the first car, and all 1999+ here are OBD2 engines
and ECU controls idle. totally. at ALL times.
post the symptoms ???

1: what year?
2: what engine. there are many.
3: is the CEL , check engine glowing running
yes, then scan it, to see the DTC errors.
4: is idle to low, say RPM hot or cold engine.
5: is idle too high, say rpm ,hot or cold
6: is idle out of control , varies. hot?


why not post the symptoms and let us guide you on the correct path.

Crv 2003 rpm up and down


hot engine
cold
or both

in drive, or park, is this a stick shift car, i dont know.

this is called surging idle. and all EFI love to do that at a drop of hat.
ALL
the hot idle is 800 rpm
bad idle surgine is caused by.
1: EGR leaking.
2: lean combustion for any of many reasons, is EFI holding closed loop status at hot idle, (no , fix that first.
3: ISC is out of control (ISC electric is the ECUs idle controller)
the ISC goes out of control easy.
EG:
a: egr LEAKS.
B. AIR LEAKS.anywhere in the induction path (AIR path)
illegal leaks, MAF engines go lean, MAP engines just race fast.

4: ISC is stuck (clean it)

with all cars. we:
1: check all fuses
2: check the CEL is it glowing running,? yes, then scan it now.
3: check with scan tool for closed loop hot. if fail fix that first.

and lots more..... but i stop here.

No power at wide open throttle


be looking at emissions controls for leaking hoses open ports etc.. is timing good? out just a bit? look at the advance system under the rotor in the distributor..does this work freely? if not..spray with lubrican just enough to free it up..

Idle Rpm Too High.


A high idle is caused by either a massive vacuum leak or a sticking idle speed control valve. I would think you have a vacuum leak, use a can of carb spray and shot around the top[ of the engine, if you hit a leak the engine will sound different, repair as needed.

My RPM fall down


That is normal. When you put it in gear, the idle speed drops about 400 rpm.
