Engine codes: 71, 52, 27
Aight guys, 1995 3.0 4runner with CEL codes blinking 71, 52, 27. My question has to do with which code to tackle first.
I know codes 27 and 71 most likely have to do with o2 sensors.
Right now I have no Cat, but it's in the mail along with 2 replacement o2 sensors (I have 2 on my truck...trust me, it's from California)
So here's the thing - should I work on code 52 and 71 AFTER I get the cat and o2 sensors in (later this week).
I feel like code 52 is pretty independent from 27 and 71, which both have to do with (most likely) air/fuel mixture or o2 sensors.
I am well aware of the large code 52 thread on the forum, and I plan on getting it fixed, but I'm curious if there is a better way to go about tackling multiple codes at a time...
