more than likely it is a bad idle air control valve or a faulty throttle position sensor or could be a faulty egr valve allowing too much air to pass thru
You also might check for vacuum leaks causing the engine to rev up and down like you were gasing the pedal might look that way if the first answer doesn't get you there easy way to look for vacuum leaks is soap and water in a spray bottle watch for bubbles. :) James.
Often times it is just a little carbon around the intake butterfly, causing it to not fully close. Spray carb cleaner on the visable carbon build up, often caused by backfires up thru the intake, you will see in the area of the butterfly and shaft. This is a very simple remedy that will most times correct the problem as it has for me several times. Inexpensive and only requires removing air cleaner or tube from top of inlet, spray n save.
vacuum leak or fuel pump Randy
The Idle Race was created in 1967.
Sounds like a choke problem/fast idle speed adjustment.
For carbureted vehicles NASCAR requires the use of a restrictor plate that goes under the carburetor and restricts the amount of fuel and air entering the engine. On fuel injected vehicles, they use an electronic engine control unit that restricts the engine to a preset horsepower.
The Birthday Party - The Idle Race album - was created in 1968.
well , it depends on your engine type .. If you are using an older vehicle (an engine without MPF-i (fuel injection)) , nothing will happen , the car will just burst to a start , that is all.. But if you are using an engine with MPFi/Fuel injection , it may damage your fuel pump , so it is recommended that you start the vehicle on idle. unless if your car is not starting , you may need to step on the accelerator just a bit .. note : If you are having a K-Series Engine , The engine may quickly jump to 6000 rpm if you raise the engine while starting , and that may damage your emission and fuel injection systems
because a 1 to 1 comp ratio would not generateenough power to keep the engine to idle,the higher your ratio the more of a powerful stroke you will have. more power is good.a i c fuel engine will be between 9;1 to 11;1 race motors on hi octane around 14;1
Too much fuel pressure, or maybe the return line is clogged, or blocked.
usually there is a fuel leak internally however it can also be an air leak
yes look for fletch's carbd 5.0 page i think its www.jason_fletcher.net? honestly it is really easy to do and is done more commonly for dedicated race cars.
There are no automobiles being built and sold to the general public with carbureted engines. They are all fuel injected and for good reason. Fuel injection allows for more precise fuel/air mixture which results if easy starting, no warm up period required, better throttle response, better fuel mileage, and less pollutants exiting the tail pipe. Carburetors are still being installed on some small engines and certain race cars but for the automobile you buy at your local dealer they are all fuel injected.
A bad IAC (idle air control)or vacuum leak. Check for bad vacuum hoses first, the IAC is around $50
