I have a 2002 Nissian Altima that keeps going into limp mode. It will rev freely but then enter limp mode for about 10 sec. I replaced the throttle body last year and that fixed the problem until recently. It was throwing a code for Intake air temperature so I replaced the MAF sensor and that didn't work. I'm Tired of this POS car and need to fix it so i can get rid of it.
