em-power Posted February 9, 2017 Share Posted February 9, 2017 Hi guys...i bought that supra and since i bought it this car have 2 problems: 1) if i go full boost , full accelartion the car start to cut power Here a video : If i drive normally and i push 70% accelerator pedal, the car run perfect untill the rev limiter! But if i push hard 100% full accelleration, than i have this power cut! 2) many times but not always...when i arrive to a corner or a stop, and im in Neutral gear, the engine switch off Not always but often. Car is 2jz twinturbo manual Boost 0,9 Only 1 catalyst (the small one before turbos) Catback blitz Decat (long one) I already changed: ICV valve, with new one. Spark plugs and all the old clips on the coils. The car dont have any FCD... But who sold the car to me said that i dont need FCD if i have 1 catalyst And boost its 0,9bar (i dont know if is correct do not have fcd??) What can i check?? Any suggestion?? Thank you very much Quote Link to comment Share on other sites More sharing options...
Alex_GT Posted February 9, 2017 Share Posted February 9, 2017 Has the fuel pump been changed? If you have increased boost pressure I think you need a higher throughput of fuel? Quote Link to comment Share on other sites More sharing options...
