I got the same message a few days ago and it was almost 40° out.I hopped in mine this morning and had a message flaah across the screen upon start up.. "watch out for possible ice on the roadways"
Or something to that effect.
And my outside temp was 30..
i didn't pay any attention to the ide speed though.
Same here. I thought it was odd that it did not go down after it warmed up.This is after it warms up to normal operating temps. It runs fine, just idles a little higher than normal. I'll chalk it up to the unusually cold weather.
Mine only goes through the this high idle cycle once per cold start. When it has reached operating temperature, it idles down to about 750 and stays there. I have noticed that if I let it continue to sit idling, it doesn't take more than a couple minutes after idling down and the cooling fan is already kicking in.Hi there.
it's been a while since i wrote anything here.
so let me start with happy new year for all of us.
I am experiencing this problem as well.
when engine reaches its normal operating temperature and weather is below 20F or -7C its idle would stay at 1100 or will go to 750 and jump back to 1100 within 30 sek. or so.
took it to a service once they replaced a throttle body but it didn't fix the issue.
then i took it to another dealer they said it is normal operating procedure for Promasters.
i get right around 14.5 avg mpg instead of 17 mpg and it is rather hard to shift gears when idle is this high.
Also i noticed that when temps are above 20F radiator fan is working all the time( A/C and defroster are off )
is it happening to all of you?
When I had my first gas PM it did the same, I read somewhere that the idle would raise when required to maintain temps in transmission, voltage and several other reasons. Totally normal. My diesel will do the same and raise the idle as needed.
