Engine jumps to 1K rpms

[chas_stevens]

All,

Just noticed my 06 PSD recently started to run the idle up to about 950-1000 rpms, every now and then at idle. If I tap the gas pedal it will return to normal idle.

I assume this is normal but can someone confirm this is or that it happens to them???

Perfectly normal. It happens on start up if the temp is 50*F or below. It's like the high idle warm up feature on a gasser.

Just helps the truck warm up.

oh ya normal. just means the truck is working properly actually. if it is just on start up.

yup...it should do it any time the oil is at air temp when its cold outside....

I find that even when hot, If I leave it idle for a while it ramps up. Could it be its for EGR cleanliness.
