Sorry for the delay. I saw your post yesterday, just in time for my laptop battery to die.
I only know the relearn procedure for Chrysler products. Some other brands are similar, and some don't show any symptoms. If you've been driving the car like this for weeks, you should have met the conditions necessary for any relearn to take place. The service advisers at the dealership should be able to tell you what, if anything, is required during the drive cycle. If they say there is nothing special you have to do, then you'll need to look at the automatic idle speed system. You'll need a scanner to allow you to command the Engine Computer to raise the idle speed to various settings to see if the system is working. Most independent repair shops will have aftermarket scanners capable of doing that. If the scanner says it's commanding a higher idle speed, but the engine doesn't respond, the idle speed motor is sticking or the air passage is plugged with carbon. We used to see a lot of carbon trouble, but that's much less common today with better additives in the fuel.
