Mass Air Sensor !!! Please help.
I have a 99 ML320 that the dealer says needs an O2 sensor and a mass air sensor. The problem has existed for over six months but they claim that they have only just found the cause. The "service engine" light has been on the whole time.
They claim that it is off warranty now and the estimate is for $1200 cdn.
Does anyone have any info on:
Past histories on this problem. Is it common ?
Thanks in advance for your help.
