Hello I purchased a AFE Takeda intake for my 2012 Civic back in April. I installed it back then and noticed a little bit of an issue when idling. The revs would be normal and about every 30 seconds or so the revs would drop to about 500 or 600rpm and cause a slight rumble in the seat. Also on a cold start the idle will fluctuate + or - 100rpm from the 1300rpm cold idle. I checked for vacuum leaks, cleaned the MAF and throttle body, installed new plugs and such over the course of the summer. I noticed that with the weather getting colder, the issue was getting a little bit worse so I took the intake off and installed the stock airbox and all the issues went away. I recently just installed the AFE intake again and the issue persists. I've tried Honda's idle relearn procedure, however I am unsure if it worked correctly or not. I've seen quite a few methods for doing this and am unsure as to which one is correct. Once the car is warm and you listen to the car idle, you can hear the times that the idle drops and its sounds like the ECU is not compensating properly for the intake and that the idle is stuttering or hunting. I'm not sure if its the ECU having issues with the new intake given the 150,000km on the vehicle or my cold environment needing a tune or something along those lines. I have the coupling well secured to the throttle body all the way to the base and then secured to the intake box just before the rubber grommet. Are there any specific torque specs or recommendations for installing this intake to ensure no vacuum leaks? Driving performance is fine. I notice the increased power across virtually the entire powerband. Would like to get this issue solved.
If anyone has any thoughts or ideas, they would be greatly appreciated.
Thanks
