2007 Yamaha YZF 600 R will not idle cold


Hey Shinji,
...Does the engine start easily..or is it hard to start? ..( I would guess a little on the hard to start side??)...How long are you leaving the choke on?? When starting the engine, you should gradually ease off the choke as the engine warms up...this will allow you to proceed and run well.. You can have the carbs adjusted to provide easier starting and run well sooner...but there are draw backs to every situation... and let it warm up before you take off...

My 1996 Toyota Camry is having starting problem. It turns over but won't start unless I floor the gas pedal. Once she's running, she runs like a charm. She starts right up when I'm driving running errands....


all cars have automatic choke system when the engine is cold the choke is automaticall at onn

you must have noticed that when the car was ok and was cold started it use to stay at high rpm and after its warm the rpm reduces

so get your choke settings checked or needs some part to change in the choke system

Check out your Thermal vacuum tree and your Thermostat. The scanner may be blaming the part when in fact the part does not have vacuum until the engine reaches a certain temperature. A weak Thermostat will prevent the engine from changing the Ignition timing quickly.

Some of the engines used water temperature as part of the choke system. The Thermal vacuum tree would route the vacuum to different dashpots and solenoids. Not only would cold temperatures activate RPM increases, but separate dashpots would trip when the engine was hot enough to run without the choke stepup and drop the RPM down to curb idle.

This made choke settings hard to set because it took so long to cool down the block to make further adjustments. The Ignition advance was regulated by water temperature so the stalling and spitting back is from retarded timing.

Remember to use your scanner to wipe the memory clean after each repair. Look for the Vacuum routing label under the hood to make sure the hoses are correct.

I have this problem for quite a bit. The idling speed when engine started cold is between 700-800 rpm. As the engine gets hotted idling rpm increase to almost 1000rpm. If idling is adjusted back, the rpm...


There appears to be a thermal movement of choke mechanism that comes about once vehicle is warmed up. Check the chock connections, hot water pipe and linkages tight or clear.

My 1986 Ford F-150 5.0 EFI runs good, but when I start it it revs to 1700 rpm untill I give it a little gas then it drops to normal rpm. How do I stop it from the high revs when started?


Does it rev high when started cold or hot? If it does it either hot or cold, check the throttle position sensor on throttle body. If that is not bad, then check the automatic choke sensor.

Sometimes to start you have to give it a lot of


Hi
This sounds like a cold start system fault, which is a number of things.
  1. Cold start temperature sensor not operating correctly so the cold start system won't work when the engine is cold.
  2. The idle needs to be set to the correct RPM of the engine when warm, if it is idling ok when it is warm then this wont be the problem.
  3. Spark Plugs are worn and need replacing.
Most case's its the cold start system not operating correctly and if you have a good workshop to take it too they should pick this up quite quickly. Hope this helps, let me know how you get on.

Your automatic choke is probably sticking. Spray it out with 2+2 Carb and Choke Cleaner. Do this when the car is cold so you don't start a fire. While the car is running see what position the choke butterfly is in when the engine is hot. If it is partially closed you may have a bad spring in the choke mechanism or it may need an adjustment.

1995 Mitsubishi L300 Van 2ltr aspirated motor, Automatic choke revs extremely high on cold start, will not decelerate till engine is hot. How can I remedy this?


If it's carburetor & has automatic choke, then there is probably a screw at side of carb, by step cam that moves with choke . Back it of a little at a time until you get desired cold idle speed. Make sure you turn step cam to setting it would normally be when cold, and choke on, then turn screw out to lower rpm's. Look for a little rod from choke shaft, down to base or side of carb area, to step cam.

Pulsar RPM or idling problem.


sounds like when you say cold you mean very cold. If your choke has variable control on it try using more choke until the motor gets warm. Often times the cold weather causes a leaner condition because the air ppm is so much greater leaving you with a leaner running condition.
