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.

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.
