Yep its the 3S-FE, I tried adjusting the screw on the throttle body, and it didnt do much while the car was idling, but it did lower the idle once the car was warm.
Ill check the vacuum hoses and also drop into supercheap or someshi* and get some throttle cleaner, where exactly is the cold start injector located i gots no idea.
Thanks alot for that guys. I'll try these things out
