Idling speed and overflow!

Sorry, but this is too much random information. What EXACTLY is the vehicle doing?
When you first start the vehicle what does it do? Easy start and even idle? Easy start and rough idle? Hard start and even idle? Hard start and rough idle?
As you hit the gas does it pause then give power? Stutter as it gives power or give power then die?
Too much information can confuse the fix.

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

Water temperature is low cost oil is certainly the easiest way is with a hard shell to block part of the warming effect of the radiator well as for how much you want to try to stop. Idle temperatures will rise up relatively low. What is the pull speed? Not run fast but continues to run uninterrupted some time. Usually two hours can be. Is to allow the engine to reach full swell purpose. Such a shift is to be based on the vehicle speed and the reference engine speed. Not based on the engine speed. Driving is probably the single 30 towards third gear, fourth gear towards forty, fifty five-speed ahead. Many people on the car ahead of change. As long as the engine sounds smooth, no trailer can be.

sometimes pulsating feeling comes from the rotors being warped and thepulling may be a badcaliper

need to clean the screen on the IAC valve.

Check the idle air bypass valve see if dirty, cleanable unit. you check the working of valve by powering the unit with 12 volts. check map sensor too.

when you turn on the a/c the ecm increases engine fuel to compensate for extra load could possibly be a vacuum leak

This may been an ignition module or a MAF sensor, this car may need to be diagnosed using a OBD I computer code reader to accurately diagnose the problem.

sounds like the idle speed sensor,if your rpm's are idling up and down

possibly a slight vacum leak?
