what causes intermittent non acceleration problem

Asked by seguinrick Sep 11, 2014 at 11:53 PM about the INFINITI J30

Question type: Maintenance & Repair

At times the car will not accelerate when stated and on one time while driving, turning off
and restarting will usually resolve the problem but it may require numerous restarts before
it works. MAF, TPS, all 4 O2 sensors have been changed as well as fuel pump and filter,
it throws code for TPS and IAC, any ideas?
