18 to 21 inches.
Idle speed is automaticaly controlled by the computer. If idle speed is not correct, the car has a vacuum leak or a sensor problem.
Idle speed is automatically controlled by the PCM. It varies from 600 to 1000 rpm. If it is not in that range then it has an electrical problem or a vacuum leak.
Install a vacuum gauge to a manifold source of vacuum (below throttle plates). With engine thoroughly warmed up and using a tachometer, turn engine idle speed adjustment screw down to 600 rpm. Start with one side idle air/fuel adjustment screw, turn it in slowly and watch the vacuum gauge. When the engine vacuum reading starts to drop, stop, then back out the screw until the engine just reaches its highest vacuum reading. Readjust engine idle speed to 600 rpm. Do this to the other side idle air/fuel adjustment screw then go back and do the first one again. After several times each you should be right on. Go back to the engine idle speed adjustment screw and set the rpm to factory specs.
No, on a fuel injected engine it can cause high idle speed.
You don't. The ECM (Engine Control Module) maintains the correct idle speed. If the idle is out of control you probably have a vacuum leak.
ABS brakes should have no effect on engine idle, but a bad power brake vacuum booster would have an effect on engine idle.
That engine should have 18 to 21 inches of vacuum at an IDLE. You can find a vacuum source on the intake manifold.
Idle speed on a 1998 Chrysler is computer controlled and is not adjustable. If idle speed is incorrect, you have a sensor, actuator, or mechanical failure. Places to start are, check for engine fault codes. Check for vacuum leaks.
The idle control valve works by regulating the idle speed of the engine. The idle speed of the engine is usually controlled by the engine of the computer.
The idle speed is computer controlled on a LT1 engine. If it is a little high, try checking for vacuum leaks.
Idle speed is not adjustable. If the speed is incorrect you have a computer, sensor, actuator, vacuum leak issue.Idle speed is not adjustable. If the speed is incorrect you have a computer, sensor, actuator, vacuum leak issue.
It is not adjustable. It is computer controlled. If idle speed is incorrect you have a vacuum leak or a sensor/solenoid issue.It is not adjustable. It is computer controlled. If idle speed is incorrect you have a vacuum leak or a sensor/solenoid issue.
