Help!

[Stani1029]

hello im in need of some expertise here as there is a problem with my car! 1st and 2nd gear work amazingly through the revs but as i change into 3rd at roughly 58mph the car lags badly until about 70mph and then you can feel the car beginning to pull again...does anyone have any idea what this could be???

as i race my car at crail this is no use at all

help is well appreciated

thanks stani :grinning:

ECU fault? well one of the sensors anyway, maybe the throttle body?

if it is the ecu would i need re-mapping?? thanks

No just the sensor / the ecu needs replacing
nissan can run diagnostics on it for you
