So, just wondering what everyone is idling at, I think my truck used to be a little higher, around 750 or so but now it is at around 500-600, and sounding sick. So, hopefully someone can tell me the right idle rpm, and two, how to adjust it. Thanks for all your help and time.

 

my 96 dodge 1500 5.9 really depends on the weather, in the summer i was at 500 to 600 75 degrees and upp. below that i idle at 300 to 400. i like the low rpm seems to react alot better.

 

warmed up, in gear, sitting in traffic I idle one white mark above 500 rpm.

 

about 1000 cold, 600 warm.

 

I idle around 500 or so. My truck idles lower then that and I know something is going to mess up with the truck

It's just like Friday 13th

 

smae here, warm i go about 6 to maybe 700 rpms, and in the cold 350, maybe 400. the cold air is awesome for the truck. mine deffinatly responds beter in the cold
