hello everyone, i have an 03 350z and the throttle went into limp mode, wont rev past 1,100 rpms. I have pulled the codes and its 1122 and 1126 i have read all the threads about limp mode and none of them really seem to apply to my problem. I have replaced the throttle body and the maf sensor,it seems if i make a hard turn is when it goes into limp, then i can clear the faults and drive, dealer told me the car is too modified for them to try and diagnose a problem like this, any help would be appreciated.

 

what mods do you have done to your Z?

 

engine mods are turbonectics kit, crawford upper plenum,mrev2 lower collector,ur crank pulley,dc headers,aem uego wideband,jwt clutch and flywheel,all the mods have been on there for awhile now and this is the first problem so far. thanks

 

did you do all the TB resets/relearning procedures once you replaced?

 

yep, once its goes into limp mode, i can reset the ecu and initialize the throttle body and im able to drive until i make a hard turn.Ive been working on it for awhile now and still havent found anything

 

probably doesnt help much, but when i had my S2000 after i made a hard right turn, the fuel system started to act up, i didnt have over a full tank of gas and it sucked up air. replaced several parts to no avail, and now i sit in a Z.

 

found the problem late lastnight it turned out to be a loose pin inside the connector for the ecu, thanks for all the replys guys
