P0170 code
Ok ive tried to do the research on this. I still cant figure it out. I have a 2005 c230 kompressor. has 103k miles on it. Last year about this time a had a code p0170. I took it to the shop they replaced both o2 sensors and this fixed the proplem. Now about a year later i get the same code took it to the shop they do a vaccum leak test its good. And they decide must be map sensor so they replace it, cleared code. And it has come back. Not sure where to go from here. Could one of the o2 sensors have gone bad already?
