how do you test a mass air flow sensor?
how do test to see if a mass air flow sensor is good or bad? iam curious to see if mine is bad, because always at start up my car idle runs little rough then it goes away and if iam sitting at a stop light the idle isn't steady, idle seems to be stumbling, but it drives well with no problems, only when the car is at a stop the idle isn't to smooth, i have new coils, new ign mod, i cleaned the iac motor, new plugs, new pressure regulator, i check the injectors and they are good, iam thinking it might be the mass air flow sensor cause when i stop the idle doesn't stay smooth its little rough? also i get no codes, if a mass air flow sensor is bad would i get service light on? or can it go bad without the service light to come on?
