Well, I had time to take the Sentra out for the second trip since I cleaned the Idle Air Control Valve. I did notice a little hesitation after I did a shopping trip at Sam's. I had to go up a hill after start-up and it was raining. So, cleaning the IACV may not solve all the hesition problems or stumbling, but for me it took care of 75%. I also cleaned the trottle body. That may have helped with overall performance. But the same black sooty junk the deposits on the trottle body gets into the IACV since it is attached to the other end of the intake manifold. I am extremely happy, since I have had the problem the last 50,000 or so and just learned to live with it. So, I can't emphasize enough the importance of cleaning the inside of the IACV. My overall performance was up 90 to 95% today. I just need to find that last thing that is causing hesitation in a warm motor, but for now, I am a happy camper! One more thing, I just wanted to bring tidings of good news and positive information to all who can benefit. If I say something that needs correction, anyone who has more experience can correct me. Peace!
