Ok guys "admins " looking around and all the post, and losts of them are about the 3 cyl and the high idle. I think that you should make a sticky up top nexted to the low voltage. includeing the. spec's for it to kick in . suck as and addtion that the smarty high idle is the same. and that this will not kick in until it's around 5 degrees or less out side due the the fact the air temp (Intake Manifold Temperature less than 0°C (32°F) .) is less than 32 degrees after the grid heaters or dual toaster ovens. as I call them.

Once enabled, idle speed will slowly ramp up from 800 rpm to 1200 rpm when all of the following conditions are met:

1. Intake Manifold Temperature less than 0°C (32°F) and,
2. Coolant Temp is less than 60°C (140°F) and,
3. The Transmission is in Neutral or Park and,
4. The Service Brake pedal is not depressed and,
5. Throttle = 0% and,
6. Vehicle Speed = 0 mph

Additionally, if Intake Manifold Temperature (IMT) is less than -9°C (15°F), and all of the parameters above are met, three of the cylinders will be shut off upon reaching 1200 rpm, creating a slight change (yea right!) in engine sound which is normal. This allows the engine to create increased heat in the cooling system, allowing more rapid engine warm up and cab heating.

Both features will automatically disable when one of the following occurs:

1. The Automatic Transmission is placed in gear (forward or reverse) or,
2. The Service Brake pedal is depressed or,
3. Throttle position is greater than 0% or,
4. Vehicle Speed is greater than 0 mph or,
5. Coolant Temperature is greater than 79°C (175°F).

Engine speed will return to normal operation at 800 rpm. If the engine continues to idle and coolant temperature is at or below 60°C (140°'F), the feature will reenable. In order to operate properly, the Accelerator Pedal Position Sensor (APPS) must stay at idle.

 

I think I have posted this at least 3 times in the past month.

HERE'S ONE from yesterday where I suggested a "sticky".

Info added. thanks guys.

 

Guys, we need to move those to the tech facts section and unsticky the threads.

 

Perhaps we need a "Sticky" to direct folks to the Tech Facts Section.
I doubt many members even know it exists.

 

Jack,
I think I sent you a PM concerning this just before you had to leave for school.
