I just got a "check engine light on". So then i went to my buddy and he scanned it and we determined that the o2 sensors on the right side bank are going bad. I was just wanting to know about how much they will run for 2x of them? Also would you just replace all 4 or just the one's that are bad? Thxs

 

Just replace the upper one on both sides. 1/2 as much $$$$$$$$$$$$.

 

How exactly did he/you determine the HEGOs are bad?

 

I'd place my money on none of the O2 sensors being faulty...

Post your fault codes.

I second that I would put my money on the O2 sensors being just fine. Check the PVC tube the rear elbow goes bad all the time. Autozone told me O2 sensors and I replaced all four sensors and nothing. So I cleaned the MAF sensor and the PVC valve and the tube and that fixed the problem.

 

On a similar note, I had the Servive Engine Soon light come on, code 171 came up, #1 bank lean. Is this the same problem?

 

I would also bet O2's are ok, What code was thrown?

My service engine soon light is on also.

I have codes

P0171 and P0174
Sysetm too lean Bank1 and Bank2

I replaced the Vacum elbow with some fuel line (is that a good idea?) it was cracked. My light is still on.

 

i believe you need to reset the KAM still? someone wanna back me up on that?

edit: i believe this is how its done
KAM reset: disconnect negative battery cable and touch it to the positive battery post. then reattach

 

I'll bet it's not the 02's as well - seeing how you got those codes - hell ,that tells me your 02's are working fine.

Since you already fixed the vac leak, I would clean the MAF and then reset, that's the procedure - in most cases , you'll be set.

 

why you quoting me? lol whatd i do wrong!!!

 

I was trying to make it look like you new what you where talking about -
