Ok so I driving along and had been for about 1/2 hour and the check engine light & check VSC comes on I went home and put my a basic code reader on it and it came up with P0174 System too lean (bank 2) I cleaned the Mass air flow sensor and reset the light all good so i thought next morning it comes on again this time its P0171 system too lean (bank 1) so i reset the light again I have done about 100 miles today and it has not come back on but it according to the diagnostics computer it is taking in 18% to much air and there for using 18% more fule does any one have any ideas please ????
