Question about Cars & Trucks
I have gotten my Honda scooter idleing thanks to your solutions, but when I give it the gas it quits. I am wondering what the function of the bystarter is and how come both of the wires going to it are hot. I do not want to purchase a new one if that is not my problem. I cleaned the carburator changer the gasoline and did everything you suggested and now it continues to idle so we're getting there. Thank you for your help so far!

Although this isn"t a proper fix, and may affect emissions, I ran accross this problem on a friend's 87 2wd wagon.
There is a dashpot that controls a lever the Idle set screw is on, I am guessing it is a decel valve that closes butterfly when coasting in gear. I never looked at a manual to figure out what controls the vacuum valve that is on the passenger side of the engine compartment, but if you disconect the vacuum line and plug it that lever will not back off and idle will remain where you set it with the adjustment screw.
Make sure the engine is warmed up and not on a fast idle cam before adjusting idle.
The car is a 5 speed, I not sure if automatic cars are the same.
The car idles fine now and still run's great and gets 37+ MPG with 240000 miles!
If you want to fix it properly you would have to diagnose why that dashpot is being actuated at idle

Lots of times the idle air control valve gets stuck on these engines. You can try cleaning it. Remove the air intake hose from the throttle body. Start the engine and spray throttle plate cleaner through the hole in the bottom on the throttle body. This will run the cleaner through the idle air control valve. make sure to keep the RPM's at about 2000 to 2500 throughout this procedure. You may need to install a new idle air control valve if it continues to happen.

did you check if the cooling fans are working? this is very important, because they lower the pressure of the freon before passing throughout the expansion valve and getting into the evaporator,more pressure means highter temperature, , of course when you are driving the air flow throughout out the condenser lowering the freon temperature in the condenser and lowering the freon pressure at the high side, tha's way the temperature inside the car is lower ... you can have a similar problem if the condenser is partially plugged..hope this was very helpful...

Drop in to an Autozone, or Pep Boys, or similar big parts store & they will usually scan for codes free. This will hopefully eliminate all the guess work, or at least point everyone in right direction for better diagnosis. If not obvious from codes what the problem is, get back to us and we'll help you out.

Ignition system sounds probable on vhicle when everything gets warmed up. High pitched hum could be bad tire or worse bearing.

Testimonial: "Thank You for your response. The huming sound is present on idle from start-up,tires have just been replaced, would fuel pump be suspect?"
