The MIL has been on ever since I replaced the spark plugs on my 98 ML. Tonight, I plugged the OBDII scanner and got the codes P0173 and P0170. From others indicated in this forum it seems that the MAF sensor is to blame. In addition I also found that the EV (Evaporative system monitor) is flashing. According to the scanner manual, it says when the icon is flashing it means the monitor has not run its diagnostic test. How do I get it to not flashing, i.e. make it perform what it's suppose to perform?
The manual mention something about "trip drive cycle", what is that? Thanks for any input.
