Cars often idle fast when you start them up. The automatic choke will make the car idles fast for a while then the idle speed will slow down, once the engine warms up.
need more info but just guessing here vacuum leak causing high idle and dieseling cause by high fuel air mix why it will not shut off
Idle adjustment set to high
you most likely have a horrible fuel sensory causing your car to be bad at idling. also you may hvae reved your engine to hard and that is causing it to idle.
Does it idle high all the time or just for a bit after you start it? There are a couple things you could check such as: 1- Defective throttle cable 2- Idle srew on you carburator is set too high 3- Choke is on Good Luck!
When I start up my 1988 cherokee laredo the idle is so high and loud it make me get very angry?
First you must check the ISC motor ( idle speed control) operation. Its located by the throttle body. It controls idle and high idle speeds. Good luck
If a 2001 Cadillac DHS sometimes won\'t start, becomes idle or just dies it\'s probably a problem with the gear box.
engine will idle high at start up same as a gas engine will. contrary to what most say, the newer diesels have same application on them as a choke. once engine has warmed up it will idle normally
idle air control valve?
Read the owners manual. find the idle adjustment screw and screw that a little. Wd40 all parts. The speed control cable may aso be causing it to never fully get back to the idle position.
There really isn't an adjustment just the IAC valve which may be dirty causing the idle to be too high or too low so the Idle Air Control valve has to be cleaned or changed.
i have a 99 Chevy blazer nd it does the same noise when idle and when in neutral it stops making the sound i was told its the catylitic converter but ive been drivin with it like that 4 a while time to time it stops for a while but don't think its that big a deal
