has 150,XXX miles. cool car to drive. very comfortable.

question time. code P0141 popped up on it. 02 sensor. which 1 is it and should i just replace it.?

Welcome to the forum! That's a nice looking car :D

The P0141 should be the rear (after cat) O2 sensor. You can check the wiring, but it could be due for changing. Is that the only code you're getting?

thank you. yes thats the only code i have. i was trying to remove the rear sensor but dam is it hard to take off on the driveway. doing it at work tomorrow. yes i was looking and it is the rear 1.
