Had codes p0173 and p170 show on obdii reader.
I checked the air flow reading and it was jumping from 1lb to 9lb at idle.
Changed the maf reset mil light. all went well fo 8 weeks.
Light came back on again with the code p0170.
So i took live reading from car.
This is what i found.
should both 02 sensors have the same reading on bank 1 sensor 1. And bank 2 sonsor 1.which they are at idle but when you drive they miles apart.
Is this a bank 1 sensor 1 fault.
If it is would it be a P0170/P0173 code.
And if it is is it easy to replace.
The car is a 2002 LPG conversion 2.7v6 4wd
Any thoughts would be great.
