PO 141 and PO 138(O2 Sensors)
Well i threw A check engine light the other day about 100 miles out of nashville. I got the codes read today and they came out to be PO141 and PO138. Some research told me these were the O2 sensors. But before i replace them i want Jeepforums take on what i should do. Which code is which o2 sensor? And I know i should avoid Boshe sensors, so what do yall recommend im on a very tight budget.
