finally got around to pulling codes
4 codes came up.
p0172- system to rich bank 1
p0152- 02 circuit high voltage bank 2 sensor 1
p0174- system to lean bank 2
p0300- random misfire
we cleared all of them and after two days of driving the only one to come back was p0300- random misfire
any of you guys have any advice on where to start checking to figure out whats going on?
