i had a mass sensor replace in my car it was a remanu one and my car was still running the same but my car is now miss firing and having poor acceleration. my guages are also out of wack. what could be the problem? i was also told i could have a bad o2 sensor and a clogging in converters
For your guage problem that could be a bad ground and for the mass air did you get a new sensor or just a remanufactured housing?
