r325

Hi all, Sorry for a bad first post but have just carried out and RB25det spec to conversion on my R32 skyline, the car starts and idles fine........ for 30 seconds, then idles really lumpy and unless accelerator is pressed will stall. Once the engine is warm runs lumpy, and really not keen on going any more the 100Km/h (3k revs) getting very close to taking the engine back out and selling is as parts :) any ideas? Steve the Pom
