Default 02 sensor

Hey everyone, check engine light lit up on the way home today after havin a rough idle and running a little sluggish. Sooo, looked up the code. H44. runnin lean 02 sensor. So my question is which sensor is correct for me to buy in order to replace? I looked up a few to get some prices, but im not sure which one is best.

Ecklers has stock replacement $75

http://store.summitracing.com/partde...5&autoview=sku
Catco(never heard of it) has one for $63

http://store.summitracing.com/partde...5&autoview=sku
Bosch $57

I am just not sure which one is correct, I know ecklers would work but its more expensive and I dont know if its worth buying if there is better out there for cheaper. thanks for any input

I had to replace mine a while ago and went with Bosch units from the local Advance Auto. Been working fine so far

I always replace with Bosch units and never had a problem with them. I buy mine at O'Reilly auto parts. Quality replacement for less $$$$

I have had the same problem in the past. Bosch worked just fine for me. They were about $50 at Autozone. Just for FYI A sticky EGR valve was the culprit causing the O2 sensor(s) to trip. I took it off, cleaned it really well with carb cleaner until it moved without sticking and put it back on.

a while back I was getting H32 which had to do with the egr valve. But it would come on randomly and than never again. Maybe ill take a look at the egr valve first before i buy the O2 sensors. Than again, i still wanted to replace my 02 sensors. Ill check the EGR first anyways

If you havn't replaced an O2 before, get yourself a 7/8" stubby wrench. Minimal room to turn a normal sized wrench.

Before throwing money at the problem and hoping it fixes the problem, why don't you diagnose the problem.
The FSM is great for tracking down problems.
