Hello! hope this post finds you in good health.
I have a k24a, 50* VTCgear, rbc, 70mm throttle body, rdx, headers. FBO setup BUT stock k24 map

car stats up perfect but has a weird sputter at 1,000 RPM when warming up. Once she’s warm, idle is a calm 800 RPM.
not sure what it can be. Ideas ?
I changed the plugs, cleaned the sensors,
Maybe a vacuum leak? Tune ?

Is that so?! I have a Ktuned TPS but I hear they mess up a lot. It’s funny you say that because I got it to 0 and 100 when full throttle but it messed up and went back to like 64 within a day
