hi got a r33 gts-t series 1 1993 i replaced an o2 sensor from just below on the right of the blow off valve, was just wondering is there more than 1 o2 sensor in the car? cause this guy said most cars have two, i replaced it and the car quit running so rich and is great but still... seems a bit too much of a smell to be running properly. or maybe its just me... so yeh is there more than 1!?!?!? and if so where is it located im guessing under the car... sigh... shud probs get the software for my box soon... as im thinking this problem entails around that...

please help!

There is only one o2 sensor.

The o2 sensor works for highway driving, where your car is sitting on 100kph for example. When the engine is running at a steady pace, the ECU reads signals form the o2 sensor and adjusts the air/fuel ratios for better economy.

It does f**k all when you're accelerating, or idling in your carport sniffing the fuel rich exhaust gas.

That's my understanding of the o2 sensor.

if ur referring to the fuel smell at idle every car runs rich on idle to ensure a smoother idle, its the newer sort of cars that run 2+ 02 sensors one b4 the cat and one after, to this is to monitor the efficiency of the cat converters operation. of if u have a v6 then u may have 2+ sensors etc etc etc

oh ok woo car works perfect! xD thanks for thattt hotpants, dsturbed..... yes it was the guy from actually my mistake its "autopro" not auto one hahahaha guess thats another -1? =S hahaha dosent matter anymore, car works perfect so i wont need to be going there anymore

    • Meanwhile, 20+ years ago, I pulled out the 105mm hole saw and went straight down through the inner guard in front of the airbox to get my stormwater pipe cold air intake in. Right behind the two stock holes for the intercooler pipes. Those have no reinforcement (apart from a couple of robust pieces of steel pipe through them!). I feel that the Australian vehicle standards crews put way too much emphasis on "maintaining the crash performance" of cars and not enough consideration of "any crash is a new and wonderful experiment with a random selection of parameters and you will never be able to tell if an extra 80mm hole through some sheet metal caused a significant difference...but if you close your eyes and squint at the whole structure, engage your engineering brain and have a good think about it, you'd have to expect that it would do jack all."
    • You guys are focussing on the wrong part of this post and have headed off on an irrelevant tangent!  Clearly I'm not going to put my most prized physical possession (well it will be once I'm finished it...) on a piece of shit contraption that might fail and crush me or my car!  At no point was that even implied I was trying to buy a butchered P.O.S that some shonky clown had thrown together with a gasless MIG....  Either way I would love to see the build quality of a rotisserie that has failed.  Actually I'd love to see a photo of one that has failed full stop.  Google fails to deliver.  Never happened?? I'll either make one that won't fail or will buy one that wouldn't fail! End Post.....
    • Yeah, if you can't breathe for more than about 2 minutes, you're cooked.
    • Well, all the power should be getting dissipated across the starter motor. Therefore, ideally, the voltage drop across the earth lead should be convincingly close to zero. Certainly you'd want it to be only a volt or so at max, because otherwise that volt doesn't turn up at the starter to do what is required. A car can probably survive a bad enough earth to crank and start with only 9V or so at the starter motor, maybe even a bit less. But you're seeing only 8V at the battery terminals when cranking, so there can't even be that much available over at the starter, which simply won't do. I would have thought that you couldn't pull enough current (with a healthy starter) to make the battery drop to 8V locally. But I was ignoring the possibility that the starter is in fact crook. If it has shorted windings (or maybe the solenoid is borked and shorting to earth) then I guess it could pull a stack of current and not even look like wanting to turn over. So follow the other boys' reccos too. Because they are just as likely at this point.  
    • Depending where the whole gets drilled, and what country/state you're talking about, quite likely not.   Under ole vehicle mod rules in NSW, VSI06 allowed for drilling of holes in "non structural" areas. So you could drill a hole through the inner guard, and not need engineering. You couldn't drill over seams, and it was advised to add extra reinforcing around the hole, as well as something to protect from sharp edges.   Again, it's all about finding the documentation for where the mod is to be done, AND then being able to explain the situation, with the documentation as to why you don't need engineering, with a positive attitude, to any one of the likes eg, police, vehicle inspector, etc.
