So I am new to this forum, just got this car in Oct. 2019. It has been completely trouble free up till this week. I started throwing the code P2004 and I understand this is the Intake Manifold Runner Control stuck open.I have the sluggish power that comes with the code and it usually only throws it after a bit of a drive. But I have been looking for the part replacement for this car under the IMRC and can't seem to find a part that fits the Nismo Engine. Also, can anyone point out where this part is located on the engine? I have been scanning diagrams and can't seem to find it anywhere. I am not new to doing car repairs but I am new to this car. I have a Nissan Skyline, 350z, 370z and a 180sx, so I know Nissans. This is my new daily driver/winter car because I am sick of getting salt all over my other ones. If anyone else has had this issue and had it fixed or fixed it themselves tell me all about it. I also found this link (P2004 Nissan - Tumble Control Valve Stuck) online, which just confused me a bit more and I am not sure if it is relevant or not. Any help would be greatly appreciated and thank you in advance.
