Michaelove Posted December 3, 2007 Share Posted December 3, 2007 (edited) I've tried my local forums but no one can come up with an answer, so I thought i'd ask the pro's Anyway! When I give my car full throttle, after about 4k RPM's it misses like CRAZY, I have absolutely no power then. But if I give it say, half throttle, I can reach redline much much easier, with slight missfire. I'm not sure if this it because of not enough fuel, no spark, boost leak or what. Maybe i'm hitting Rich and Retarded? RB25DET t3/t4 Turbo 10psi of boost I need new spark plugs, so I'll also ask which spark plugs I should get. Anyone have any similar problems? Any help is appriciated. Thanks! Edited December 3, 2007 by Michaelove Link to comment https://www.sau.com.au/forums/topic/196213-major-problem-rb25det/ Share on other sites More sharing options...
