Hi guys. Can someone tell me why my 4g63t is idling like a ported rotary? Also do i fill my transfer case (c73a) with oil itself or does filling gearbox do this? Cheers

Sounds like maybe its not firing on all cylinders, that's just a guess though. Any codes from the computer or can you post a video of it running? Transfer case will have its own drain and fill plugs.

Thanks for that. I dont know how to read code. Theres no check engine light on but im guessing you can get codes anytime off the ecu. I could try upload a video it just may take a little while. Thanks again

It could also have a vacuum leak somewhere causing the brap brap idle

Cool thanks. I cant valve bounce the car either if this is contributing towards problem. Its not liking high revs

Unfortunately, a rough idle can be caused by lots of things. If you have a vacuum leak, chances are it will turn into a boost leak whenever you're boosting, which will cause the car to run rich and decrease performance. You could also have incorrect cam timing, which will make it idle rough and REALLY decrease performance. You could also have a bad ECU, or a bad MAF. You could also have a mis-fire.. Start with the easy stuff and work your way through the car.
