ok so my car is running better since i changed out the pcv valve vac hose but still a lil rough and trying to die when its cold so im thinking about checking or changing some sensors since my stang has 83k on it ... i have no check engine light coming on but i have heard that sometimes the 02 senors can get slow with age and also the iat sensor ( what should my intake temp be anyway) and then of course the maf sensor ... is there a way to check any of this with my sct tuner ... thanks for any help
