SOURCE: Engine surge during warm up.

Try changing your PCV valve make sure the hose is clean and not full of oil. Also check the elbow end that goes to the intake they tend to collapse from oil saturation. Hope this helps.

SOURCE: my toledo v5 has a jumpy idle

Do you perhaps have a small exhaust leak? Check ahead of the O2 sensor. If the exhaust can **** fresh air in it can't give the computer an accurate reading and the engine will rev up and down at idle. Hope this helps.

Why does my 2006 suzuki escudo idle too high once the engine has warmed up, almost like the automatic choke is jammed on but revs are higher than when choke is on


first off no 2006 has choke, i now you are not here, in uSA.
this engine, no size stated or name.
IS this the G16 engine, post a photo of engine,, and we can tell you, every time.
here are the engines used on all 2nd gen Escudo's

1.6 L G16B I4 (petrol)
2.0 L J20A I4 (petrol)
2.5 L H25A V6 (petrol)
2.0 L RF/RFM I4 (diesel)
2.0 L RHW/RHZ I4 (diesel))

the g16 never races, if there are vacuum leaks.
it stalls. or low RPM
high RPM on this G16 is caused by ISC failures.
we clean them every 60k miles, like the book asks.
this engine has EFI , electronic fuel injection and has 16valve head, and the fuel is metered via a MAF sensor.
the ECU controls hot idle all them time
there is a cold start air valve, called IAC,
this is pure thermal device below the throttle body.
and can stick open ,
or the engine does not reach 180f the ISC will no close
even a newone will not close until 150f is crossed !
also not getting coolant changes, the water line to the IAC valve will clog and make it fail, clean that clog and it now works
also the TV can gunk up

see that throttle body , inside is the TV, the throttle valve
it can do this.

this G16 site covers all failures

gunk 101 clean it, or the TV sticks open

How can I fix high idle?


In theory once the desired idle speed is programmed into the management system, in the absence of such faults as air leaks, sticking idle air control valve and suchlike it should be impossible for the idle speed to be much different from the programmed value because the ECU should continue closing down the amount of air bypassing the throttle butterfly until the idle is around the correct value.

I think you need to go back to basics and double-check the work to ensure everything is as it should be. In the absence of mechanical faults and ignoring the possibility of electronic problems a high idle must be caused by too much air entering the engine, either because the idle air control valve is not closing properly or because the throttle butterfly is not closing fully.

It is worth noting air can enter the intake through leaky diaphragms, split vacuum hoses or faulty pcv systems. It is also worth checking the egr valve if fitted.

How can I lower my IDLE?


I have heard that air in the coolant will affect the idle speed, also a vacuum leak.
Your English seems perfect to me.

1998 Civic, Cold start, idles fine. When car is warm idle speed increases then decreases over and over again from about 600 rpm to 1100 rpm. once warmed up and driving throttle becomes on-off...


it could be the MAF sensor or the air temp sensor, it could also bet the idle sensor, it would be best to put the engine on an ecu reader to read live data as it would show at what temps the senors are working at some times it may not trigger a fault, but live data will tell you at what temps the sensors are say they are and you should be able to see what one is not working right. i would think it would be Maf sensor when was the last time the air filter was changed. if its really dirty change it and also use some MAF sensor cleaner you can buy it from a range of places and clean the MAF sensor. be careful cleaning it only use the recommended maf cleaner as other chemicals will damage it. remove the sensor from the rubber pipes a spray the cleaner on the the sensor an a bit of paper towel give it a good clean with the spray and leave it to dry before refitting. some people use carb cleaner but would not recommend it.

Volvo v40 2000nx reg 1.8 NON gdi engine constant high rpm can having no thermostat cause constant high rpm or can a briken lambda sensor cause high rpm cleaned all throttle body cleaned idle valve checked...


Yes, having no thermostat can cause the car to run fast as it will still be set in it's "warm up" mode and will be injecting a richer mixture of fuel/air into the cylinders. There may be an additional cold start injector that just works while the engine is cold. You will probably use more fuel like this. It's not a great idea to run with no thermostat anyway because you get uneven hot and cold spots around the engine which is bad for it. Cheers

I replaced the timing belt now the car has a very high idlewhy


Its most likely a vacuum leak or the throttle needs to be adjusted. Check that there is a small amount of play in the throttle cable between the bracket on the back of the intake manifold and throttle body. If there isn't, the throttle body may not be closing all the way.

Other possible causes:

The coolant temp. sensor is giving an incorrect reading. When the sensor reads a low coolant temp., like when you first start the car and the engine is cold, your idle will be high. As the engine warms up to operating temp (about 200 F) the idle speed will decrease. Idle speed should be around 750 rpm when the car is fully warmed (800-850rpms fully warmed with a/c on).

The idle air control motor may be stuck open.

I have a 97 Blazer, just had the fuel pump replaced and worked fine. But in the cold weather it won't start. Any tips?


Try energizing the fuel line twice, turn the ignition key to the on position for 30 seconds then turning it off for 5 seconds and then try starting the engine. This will warm up and clean the MAF sensor, and also ressurize the fuel line if the fuel pressure check valve has failed and that is located on the fuel pump return line. Clean the MAF sensor will also help in the cod weather starts, so you may want to clean the MAF with MAF cleaner and clean the Throttle body with throttle body cleaner and pay attention to the Idle Air control valve passage ways at the back of the throttle body opening. Good luck and keep me posted.

Idle out of control.


check all your vacuum hoses and the throttle body itself for a vacuum leaks if the hoses replace as nessasary if to check for throttle body get can of carb cleaner and spray around base of throttle body and sides not in it if idle raises you have a vacuum leak goto a good parts store and ask for a rebuild kit don't goto auto zone or advance they don't carry them

1990 Honda Prelude 2.0 si F.I. Idle Fluctuation


This problem is a little bit hard to coz you need to check the following throttle body, fast idle valve & the IACV valve. First the throttle body it must fully closed during idle and the TP sensor voltage must be 0.5 volt. The fast idle valve is wax type there is a 2 small hose pass below of this valve, if the coolant water is not circulating the valve will not closed. You can check it by touching the lower portion of this valve after 1 min. Regarding the IACV you can check if this is the fault by removing the hose connecting the throttle body and air filter. there is 2 small hole near the opening of the throttle body, while the engine is running at idle close one by one and see which one cause this problem.I hope this will give help to your problem.
