SOURCE: will not drop down from fast idle when first started

It sounds like an automatic choke system. Let it warm up for 5 minutes and then give it gas up to 2000rpm and release.

SOURCE: ryobi cs30 starts fine, but idles way too fast

you need to take your air filter off and look into the throat of the carbruetor to see if the ""Butterfly""
is still intact and working not the choke butterfly its the one closest to the engine that moves with the throttle and be sure it is still there and moves as you move the throttle.... open is horizontal and closed is not quite 90 Degrees. check to see it is tight and in the center if the throat when closed.
you may have to remove the carb. to see it function more clearly
make sure the throttle cable is free and not binding any where and to be sure of its adjustment to allow the throttle to return to the idle position.
lubricate the cable from the trigger to carb. wd 40 is ok.
if all above is ok then find the L on the carb. and ccw it 1/8 turn to ritchen it alittle to help slow the idle down some to a respectable level

SOURCE: 2002 Honda Accord V6 check engine light on- local

po505 idle air control if this is the code all hondas do it eventully, small problem easy fix u have 2 choices either remove the idle air control motor and clean the inside of it u will find it's black and the spring inside is stuck clean it with carb cleaner or gum cutter any parts store will have this it's a dirty job it will work for awhile but to replace it is recommended its not expensive for a new one which u can get at any autoparts store autozone,advanced,napa etc. there is only 2 bolts in most cases maybe 3 i doubt it though if u go online t google and type in th eyear make and model and engine size in ur case it's a 3.0 v6 and look for idle air control locations u'll find it to do this job a shop will charge u anywhere from 100.00 for diag to retrive the code plus the part and the labor so about 250.00-375.00 it will only take u honestly maybe 15 minutes to perform only tools needed are a 10 millimeter wrench there is only 1 connector to disconnect and ur done if u do this u will still have the check engine light because u have not cleared it from the computer to do this just disconnect the negative battery terminal (the black one or has a neg sign - don't disconnect the positive side +)for 5 minutes then reconnect and the computer will have reset no more light. good luck it really is that easy

SOURCE: I have a 1987 Susuki Samurai, 1.3 engine. Cold

Yeah it sounds kinda high. There is no adj except for the idle screw on the throttle, the computer does the rest, if it has one. If not, then you can adjust it some how. If carbureted, check for 2 little screws in the front, and check the choke, If throttle body, then just the idle screw, the idle should be around 1000. Hope this helps.

Greetings. I have a eu2000 honda inverter with the following problem. The high generator runs too fast, when the idle is activated, slows down a bit, but does not increase


on the governor control back to the carby , there is a screw that adjusts the spring tension for the governor arm
that screw is the adjustment for engine operating rpm not the idle screw

Honda crx with auto transmission idles roughly in drive or reverse. AC on makes it worse.


There are two coolant lines that connect to this Honda IAC to help quiet the operation of the valve. The part number for a OBDI 1992-1995 Honda Civic Idle Air Controller is 36450-P28-A01. While the OBDII version of this valve is 36450-P2J-J01, and the two units are very similar in design and execution. The EACV or Electronic Air Control Valve is a big part of maintaining your Honda Civic idle. If you've checked your IAC and your Honda still suffers from a surging idle, check your FITV. This Honda Idle Air Controller or IAC is under the throttle body and incorporates into the throttle body passages o locate your Fast Idle Thermo Valve, remove the intake snorkel and locate the FITV beneath your throttle body opening. If your SOHC engine is still having problems, check our guides above on how to check your FITV as well as your IAC. To check this operation, remove your air intake pipe and use your fingers to plug the passages in the lower left hand corner of your throttle body opening. If your idle surge does not go away, unplug your Idle Air Control valve and if that stops your idle surge, your IACV must be replaced. Follow our instructions on how to replace your Honda Civic Idle Air Control Valve. Need to raise your Honda Civic idle or having problems maintaining idle? You can adjust the base idle by unscrewing or screwing in the Idle screw on your throttle body. This screw allows air to bleed into the passages on the backside of your throttle body, as shown above. To learn how to adjust Honda Civic idle speed, you will not need to remove anything. With a standard screwdriver, simply locate your throttle body and Idle screw.

How do i stop the engine running at a fast idle


Assuming it is a completely mechanical system with no electrical or electronic control there is no actual fast idle facility unless it is provided by a Waxstat cable device fitted into the cooling system.

I think what you mean is the engine idle speed is too fast rather than it is running at "fast idle" which is a term used for a raised idle speed when an engine is cold and decreases as the engine warms until at normal operating temperature the idle speed should be normal. On an old diesel engine it is the Waxstat device if fitted that provides this facility or a hand operated throttle. Very old cars and trucks had hand throttles for fast idle but later this function was provided by the choke or strangler mechanism. Some luxury cars had an electrical device fitted but the fast idle of modern engines is invariably provided by electronics.

I expect you need to adjust the throttle stop screw of the injection pump. This is at the lever where the throttle linkage connects to the pump and there is generally two stop screws fitted that limit the travel of the lever. One screw limits the maximum travel of the lever and therefore the maximum engine speed and this is generally set during manufacture or remanufacture and sealed to prevent tampering.
The other screw is the idle screw which the lever is pulled against by a spring when at rest.
Before adjustment it is necessary to ensure the throttle linkage is not maladjusted and preventing the lever contacting the stop. Disconnecting the linkage until the idle speed has been adjusted will ensure this and then slacken the stop screw locknut, start the engine and turn the screw in or out as applicable until the desired idle speed is achieved, allow the engine to warm up and make further adjustment if necessary and tighten the locknut and reconnect the throttle linkage. Do not adjust any pump screw except the idle screw.

Good luck!

I have a 2007 cbr600rr, and I have noticed lately my bike idles around 1900-2000rpm, normal is around 1400-1500rpm(this is when the bike is warm), also when using the engine for braking it feels a little...


Hi, Anonymous and the usual suspects are:
1. Throttle cables improperly adjusted, pinched or need lubrication.
2. Idle adjusting screw needs to be backed off.
4. Air fuel mixture adjusted too lean start with 2 full turns.
5. Intake system air leak.
6. Fast idle choke ramp is not releasing.
7. Broken throttle return spring.
8. Damaged diaphragm or slide.
9. Faulty MAP, TPS, ATS, O2, sensors or wiring/connector

Where is the throttle screw(for idle speed), of the carb, in honda activa


That idle adjustment screw you are looking for can be found just below the fast idle cam. Which is connected to a spring-loaded hinge with a throttle cable attached.

Kescorpio56:
Check your throttle and choke settings. Something is causing the throttle plate in the carburetor to remain open or the governor is improperly set. I would reset the air/fuel mixture screws to one and a quarter turns out and back the idle screw all the way out. Make sure that the throttle cable operates the throttle properly and check the governor setting and reset the governor setting if needed. Start the engine and adjust from there. When the engine starts, adjust the idle screw until the engine idles. Adjust the fuel/air mixture screws for the best idle. Then run the RPM up and adjust the fuel/air mixture screws for the best run/idle combination. Don't forget to adjust the governor if the engine runs too fast or too slowly.

I have a 1991 honda civic hatch with 1.5 engine idles fast cold and hot and ECU flashes twenty times


Hi Jason, I suggest you take the vehicle and have a diagnostic scan carried out. Doing that will pin point the problem area and take out the guess work. I have known occasions when someone has tried to adjust the throttle butterfly, hoping to reduce the idling speed and by doing that have taken the TPS (Throttle Position Sensor) out of the correct adjustment, causing abnormal idle speed. Regards John

Honda Accord 1991 idles high then low


)The fact that thge engine idle fluctuates when it is cold indicates that the Fast Idle THermo Valve is out of adjustment.
This valve is located ot the front of the intake manifold on the driver's side just below the accelerator cable. To adjust it, wait until the engine is cold (best to do it first thing in the morning).
Remove the two screws holding the cover on and start the engine. There is a brass needle sticking up through a plastic ring that has two slots in it. With the engine idle fluctuating, use a thin flat blade screwdriver to SLOWLY turn the ring CLOCKWISE
until the idle stabilizes. Once done. put the cover back on withg the two screws and you should be done.
