Ok its probably a really simple question and answer, but im going to ask it anyways.


My 97 dodge ram 5.2L idles around 500 RPM when it is warmed up. What i want to know is what is the correct idle speed for these trucks?

I believe that the truck is idling rather low, but im not sure and i would just like to get everyones two cents.

 

I'm pretty sure right around 600rpm is where you wanna be.

 

Does idle up if you turn on air and not lug down? If so, you should be good. 500 is a little below where most of them seem to be. If there is a concern, disconnect battery cable, remove IAC and clean it and the port and try again. See if that increases a little.

 

my air conditioner does not work due to a bad compressor so i dont think i will be able to test out that theory.

 

Wuao!!!! So am wondering why my truck idles at 1000 rpm after spectre cai?? It feels like ur puching the gas really slow after stops signs. :-(; ?????

 

Sounds like your problem is a vacuum leak.

 

600RPM. I wouldn't trust the factory tach, if I trusted mine I'd believe the idle varies from 400-1200.

 

iiiii

 

This section of the forum is for 2nd gen gas trucks... Not 4th gen diesels.

Your post is kinda hard to follow, but if I'm reading it right I'd guess that it's normal. The truck should go into a 'high idle' below a certain temperature to aid in cold weather engine warm up.

Ask your question in the diesel section or on cumminsforum.
Ps, it's a 6.7l engine not 6.9
