2002 Yukon Idle Speed

Well Ive provide actual data from a stock tune so he can get closer to resolving his issue. When someone guesses, and someone hears it, they pass that info along as fact the next go round. That's how we become dumber. I wish if people didn't know they would be quiet and wait for someone to come along that does (this isnt aimed at anyone in particular), so only the best/most accurate info gets passed along.

yeah i make it a firm policy of only providing factual information when responding to a question or helping someone troubleshoot hell sometimes when i know exactly how to fix a problem or exaclty whats wrong ill go research real quick to confirm before i post

okay i just did a little maintenance today and while i was at it i plugged my elm 327 and pulled up the live data in torque the ob2 app and my tahoe idles in the 595 to 605 rpm range and thats the stock tune

So in other words what your saying is that his idle stumble with ac on while turning at low speeds/idle is normal ? I dont have those app data viewer I have what is call a Tech 2 with a candi module not sure if your familiar with and hook that thing up on a daily basis to scan GM vehicles for everything from airbag lights to ALRC module... EBCM... HVAC... VCIM... PCM/ECM... TCM.. IPC... TAC module.. Software updates... this thing does it all yes the TACH is not always dead on on the IPC but one thing I can tell you is my 02 U motor and wifes 04 Sub T motor, with all the latest GM software updates to every module on my vehicles that I programmed myself and every other vehicle I work on with in that range keeps an idle above 600 with AC on Idle will dip slightly below 600 with absolutely no stumble with P/S load and thats looking at Tech 2 data.. and believe me I would never be able to get away with telling a customer that that is normal..

A slight dip is normal, a stumble isn't. I suggest a tune up in my first post. That meant a thorough examination of most items under the hood, hoses, filters, and anything else that might look suspect.
