So i pulled this code a couple of days ago after i did my plugs, and now my car is running weird.
0210 for Fuel System Lean/Bank 2

Seems to be its a problem with the 02 sensor. Now question is, how many 02 sensors does my car have, and which one am i looking to replace with this code?

Please help.

Thanks

But they're supposed to be pre gapped. I especially asked the technician, and he said not to tamper with it since its been already made to specs.

 

^^ yeah you should not have to gap the plugs.

I would guess o2 sensor, and its just a coincidence that it happened after the plugs were installed.

There should be two sensors on the y-pipe, one below each exhaust manifold.

just my guess...

 

you may not have to gap your plugs but you should always double check the gapping the make sure they are in spec.

 

You should check for air leaks before replacing o2, who knows, maybe you popped off an evap line for more access to a plug and forgot about it?

 

why you not reply to my PM

 

yea i was told the same thing by a tech and they ended up being way off, i was to lazy to check them and threw them in and a couple days later my car would barely run.

 

NGK recommends gapping copper plugs.

iridium and platinum come pregapped and tempered so if you mess with them they can crack like brittle wood

 

yeah i have iridium plugs, and it even says on there that they're pre gapped.
Anyway, anybody know which 02 sensor i'm supposed to be replacing? I already have one laying around, so might as well use it.

 

Bank 2 = closest to radiator

 

How many does the 4th gen have? Are there 2 in the front area or was my eye just playing tricks on me?

 

Depending on emissions spec, the VQ30 can have one or two O2 sensors for each bank. Fed specs will have another after the main cat, whereas cali specs don't (IIRC).
