Beavis Posted May 5, 2013 Share Posted May 5, 2013 Might be worth doing the ecu and throttle body reset by the metheds in this link. http://www.350z-uk.com/topic/53148-ecu-accelerator-pedal-throttle-valve-resets/ Quote Link to comment Share on other sites More sharing options...
aidan Posted May 5, 2013 Share Posted May 5, 2013 Maybe obvious..but recheck battery connections. Could a loose connection cause fuel pump not to get full power...or something along these lines? Also when you started it after battery disconnected...did you have foot on gas? again not sure about 350z...but Evo ecu learns after battery disconnection so always let it idle for 10-15 mins before taking it for a spin.

Y23DRH Posted May 5, 2013 Author Share Posted May 5, 2013 i have to go high wycombe later so will take it for a spin and see how it goes hopefully will go back to normal worth a try i guess maybe just needs a long run Quote Link to comment Share on other sites More sharing options...
Y23DRH Posted May 5, 2013 Author Share Posted May 5, 2013 very odd took it to high wycombe drives fine there and back rev the throttle at a stand still seems fine so its only when it starts now that it cuts out weather hot or cold if i touch throttle when starting stays running no problem if you don't touch the throttle then it cuts out about 2 or 3 seconds later :? very odd was fine before the reset :/ any ideas or no a good place to take it to after the bank holiday Quote Link to comment Share on other sites More sharing options...
