Cracked exhaust manifold near o2 sensor was the problem

Poor gas mileage, crappy acceleration, and of course your CEL is telling you its bad.

 

im getting the cel for it. but Im still getting good gas mileage and acceleration is fine once it warms up.
When it's not warmed up it bogs a bit during acceleration.

 

I know it all depends on how you drive but what is good gas mileage compared to bad? I have a 99 GS

 

what year is the car?

 

Sigh..............................The computer reads the o2 in closed loop only. If u had a scan tool, you could see what the o2 is doing. Do u even know what your doing?

 

You have a CEL so fix it, i don't understand the need for this post, when you could've used the search button.

ok I'm looking for a new O2 sensor for a good price, from what everyone says the factory one is the Denso 234-4011 which I found for $85 plus shipping. I am wondering of the universals will work just as good like Denso 234-4209 which can be had for $45 plus shipping
Has anyone gotten these and tried to just splice the wires? Anyone try a different brand and have good results? I did a search for O2 sensors and this is the cloese thread to the results that I am looking for, some feedback would be great, thanks

I just looked on that page and saw a universal part # 29415 for $29.85 and thats for the front, is that the one you got? there is a rear one part # 24546 for $139.85. If it's the universal one you got, don't you have to splice the wires? I don't mind doing that, just wondering if they work as well,
anyone else have two cents to share?

 

I bought a BOSCH one recently for $68, Universal, it was a breeze to splice in.

 

Um, one symptom is a check engine light. You have that. Replace the sensor.

actually it was a crack in the exhuast manifold where the o2 sensor screws in

 

how big was it? Any pics?

 

so has anyone gotten the universal NGK part # 29415 for $29.85 and spliced it? Anyone else use a different brand universal?

 

Hey, you don't have to re-drill and tap for the universal O2 sensors right? I thought you just needed to re-splice them, but my one friend is telling me different

 

Many people said when you have a CEL code 1 you should replace the O2 sensor, but is there any other problem that means the engine is not healthy? O2 sensor detects the O2 from the engine. I also replaced an O2 but sometime is on also about once a month!
