p0170& p0173
had got both codes a week ago did a search and found the mass air flow could be dirty
cleaned mass air sensor with brake fluid worked for a week tonight again check code s and also found long tern fuel trim at 27% on both banks short term -2% Intake manifold pressure one time 13in Hg and 10in HG last time What I am asking is the mass air sensor going??? I could not find any vacuum leaks I also checked fuel pressure lookd right on replace fuel filter because it needed to be changed Is ther any electrical checks to do on the mass air flow sensor??? The vechile is a 2000 sl500 56000 miles any tips would be appreciated
