Is there any way to adjust the cold idle speed on ford ranger 3.0


There is a base idle speed set at the factory . From sensor inputs the PCM - engine computer controls idle speed in all conditions . There is nothing for you to change idle speed, you shouldn't even try . Will cause PCM to turn on the check engine light ,that you won't be able to turn off . If your having idle problems your best bet have a qualified repair shop check scan data .

How to adjust the idle speed on 1992 Dodge Ramcharger?


Its not really adjustable.
The computer controls idle speed via the idle air control valve.
You probably have a vac leak.

Truck dies when idling


HI
first I would like to tell you, do this procedure only if the 5th digit of your VIN is C or K.

Description

The engine control module (ECM) learns the idle position of the throttle plate to ensure the correct idle. Anytime the throttle body is cleaned or replaced, the ECM must learn the new throttle position. The idle may be unstable or a DTC may set if the throttle position is not learned.

Conditions for Running the Throttle Learn Procedure

• DTCs P0101, P0102, P0103, P0107, P0108, P0111, P0112, P0113, P0506, and P0507 are not set.

• The engine speed is between 450-4,000 RPM.

• The manifold absolute pressure (MAP) is greater than 5 kPa.

• The mass air flow (MAF) is greater than 2 g/s.

• The ignition 1 voltage is greater than 10 volts.

Throttle Learn

Important: Do NOT perform this procedure if DTCs are set. Refer to Diagnostic Trouble Code

(DTC) List - Vehicle.

1. Start and idle the engine in PARK for 3 minutes.

2. With a scan tool, monitor desired and actual RPM.

3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease.

4. Ignition OFF for 60 seconds.

5. Start and idle the engine in PARK for 3 minutes.

6. After the 3 minute run time the engine should be idling normal.

Important: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.

* If the engine idle speed has not been learned the vehicle will need to be driven at

speeds above 70 km/h (44 mph) with several decelerations and extended idles.

7. After the drive cycle, the engine should be idling normally.

* If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds

and repeat step 6.
8. Once the engine speed has returned to normal, clear DTCs.
Good Luck

Engine speed decrease when stert the AC


IDLE AIR CONTROL VALVE IDLE SPEED TOO LOW. IDLE SPEED SHOULD BE 750 - 850 RPM. IDLE SPEED NEED TO BE CORRECT OR IT WILL CAUSE ENGINE RUN ROUGH OR STALL OUT.AC COMPRESSOR WILL TAKE SOME POWER FROM ENGINE WHEN AC IS OPERATING.

I am getting a code of p0506 from autozone. How can this be fixed?


DTC P0506 refers to the actual engine idle speed not being within range of the commanded engine idle speed. If there are any other DTCs present those must be fixed first.

This can be caused by an ISC (Idle Speed Control) motor sticking.

Other possible causes of this code are:
- incorrect TCC (Torque Converter Clutch) operation
-accessories that require additional engine torque to operate - including amplifiers, security systems, etc. that can cause additional electrical load.
- Restricted exhaust system
-any other mechanical problem that may affect engine speed.

I have a 1998 Acura 3.0 CL and the radio had an error 3 last week. I had to take the console and radio out in order to find the radio serial number and got the radio code from Acura, since mine was...


I don't see this as related to the console. This issue is usually caused by the idle air control valve. The valve may be bad or possibly the wiring. If it's the wiring, normally the computer will turn on the engine light.
You can check the valve operation using a common obd2 scanner in data mode.
Here is more info from autozone.com:
Engine idle speeds are controlled by the PCM through the Idle Air Control (IAC) valve mounted on the throttle body. The PCM sends voltage pulses to the IAC motor windings causing the IAC motor shaft and pintle to move in or out a given distance (number of steps) for each pulse (called counts). The movement of the pintle controls the airflow around the throttle plate, which in turn, controls engine idle speed. IAC valve pintle position counts can be observed using a scan tool. Zero counts correspond to a fully closed passage, while 140 counts or more corresponds to full flow.
Idle speed can be categorized in 2 ways: actual (controlled) idle speed and minimum idle speed. Controlled idle speed is obtained by the PCM positioning the IAC valve pintle. Resulting idle speed is determined by total air flow (IAC/passage + PCV + throttle valve + calibrated vacuum leaks). Controlled idle speed is specified at normal operating conditions, which consists of engine coolant at normal operating temperature, air conditioning compressor OFF, manual transaxle in neutral or automatic transaxle in D .
Minimum idle air speed is set at the factory with a stop screw. This setting allows a certain amount of air to bypass the throttle valves regardless of IAC valve pintle positioning. A combination of this air flow and IAC pintle positioning allows the PCM to control engine idle speed. During normal engine idle operation, the IAC valve pintle is positioned a calibrated number of steps (counts) from the seat. No adjustment is required during routine maintenance. Tampering with the minimum idle speed adjustment may result in premature failure of the IAC valve or improperly controlled engine idle operation.

TESTING The IAC can be monitored with an appropriate and Data-stream capable scan tool

Engine idle speed too fast some times. idle speed


Three things to check for:

1) High idle switch is on..*(vehicle thinks AC is running but it isn't.
You can try turning on the AC and see if the engine slows down to confirm this one.

2) Sticking or worn out Idle Air Control or IAC, You might get a check engine light with this one.....you might not if it's a mechanical failure.

3) Simplest of all. A vacuum leak. You can get the engine vacuum read while running if you go to a mechanic with a vacuum guage or an OBD 2 ecu code reader. There should be specs on what vacuum levels are normal for you car at idle.

Good luck and be careful!
