normal operating idle

what is considered normal idle RPM? i have 02 TRD with 3.4L V6. right now truck idles to 1200 when cold than drops to 750, when warmed up.

 

Are you in Neutral? Do you have an Auto? If in park or drive that sounds about right.

 

Idle range should be set anywhere from 600-800 rpm after warming up. 750 isn't bad. The idea is to not have it so low the engine is taxed to stay running which will cause damage.

 

thanks much.
Its 5 spd, i start in neutral, let it warm for 4 to 5 min, than it takes about 4 min of driving for RPM to come down to 750.

 

That sounds normal. Just like what mine does.

 

'Spec' idle speed is 700 rpms, + / - 50 (i.e., 650 - 750).

 

Yeah, I got a 2001 V6 a few months ago, I was was trippin' at the seemingly excessively high RPM on warmup (1500 right after I turn the key, foot off the gas, then settles to 1200), but what you describe is exactly as mine does.

I could only find the idle spec for when it is warm (should be under the hood on the emisisons sticker), not a range during cold start. I leave my house every day tooling through the neighborhood in second gear with my foot off the gas until it warms up...

 

sounds normal to me

 

sounds like a happy taco to me
