I threw p0171 & p0174 codes on my 2005 SRX RWD Northstar about a week ago and when engine has not warmed up, idle rises and falls in park. I checked for va***n leaks and found spraying carb cleaner under the rubber coupler that connects the throttle body to the intake manifold cases the idle to level out. My question is, does anyone know the part number for this coupler? I figure the leak is there but I don't want to take the intake manifold off unless I have a replacement part handy, and the stores around here cant find the part in their system.

 

Have you find this part for your car ? I had exactly the same car, and I am sure that I knew the part number, but, unfortunately I forgot it. I wish I could help you, but I can't remind what was the number. However, I am sure that it was ending with 838. Maybe, it is going to be useful for you. By the way, did you know that it's a special number? I have recently read on https://www.sunsigns.org/angel-number-838-meaning/ that it has a special power and meaning. This has actually shocked me.
