I have an 02 nissan sentra, the check engine light came on and the codes were pointing to the mass air flow sensor, since the car was loosing power and not accelerating, I replaced it. there is now a whistling noise (there was before too) and I still am not accelerating. I can get up to 20-30 then even the smallest hill will make me drop to 10mph....the car wants to stall even while driving, although it hasnt...yet. what could it be? Plugged exhaust? Im getting fed up am about to take it in to get looked at...oh and I also checked for vacuum leaks and that I can tell there is none
