Hey guys, I was wondering if the bosch oe o2 sensors just were perfect replacements or do you have to cut and splice any wiring. One of my buddies said he had to do the cut and splice thing on his car once....but he may have tried UNIVERSAL ones? Just checking before I go to buy them from Autozone--- Thanks

 

If you cut the wires between the weather pak connector and the sensor it makes the sensor useless. The only ones that will work are the ones that will plug directly into the harness.

 

Do NOT buy Bosch O2s.
Most will agree -for our cars, for O2 sensors ONLY use AC Delco.

Search around. You'll see.

 

ONLY use AC Delco.

 

I've ran my Bosch 02 sensors for nearly 3 years....no problem.

 

And your 93 also has different O2 sensors than every other LT1.

 

That is true, just single wire O2's.

Good you pointed that out, I wouldn't have thought of that.

 

SO are the 93 and 94's BOTH different in the O2 department??

 

93s have one wire sensors and all later models have four. The front sensors are the same 1994-1997 (1994-1995 has only front sensors).

 

Cool, thanks for the info!

 

Who carries AC Delco ones and how much are they?! I need them sooner than later. Also how many o2 sensors do we have?! The bosch are $55 and I found a site with WALKER brand ( never heard of ) and they are $50. Also I've been told I can run a SIMULATOR to where I only need one working o2 sensor (where do you get those and how much?!). If the simulators are as much as the o2 sensors what are the advantages to running them?! The codes I am throwing are passenger side front 02 and driver side rear 02 so I am guessing there are more than just these two right? THANKS GUYS!!!!---

 

First off, the simulators are not expensive if you know where to look. Get this 2 channel one from here.

With other units costing more, you are probably paying for the connectors and the ability to plug it in and go. The ones I posted above have to be spliced into the wiring.

The purpose of the simulator is to take the place of the rear O2s which are only in place on OBDII vehicles to confirm the efficiency of the cats. They do not effect the air/fuel ratio. Therefore, if you want or have to remove the cats, the simulators will elliminate the pesky SES light for cat efficiency.

Second, if you want the EXACT same O2s as OEM but with a different name on them, and save some moola, go here.

All GM O2s whether they say AC Delco, GM or Delphi are made by a company called Standard Auto Parts. These are made to a more exact tolerance. The ones sold by Bosch and others are made to be used in several different applications even though the connectors each one has may be different. That is to keep them from having to buy so many different part numbers. In this event, they are made to cover a broader range of vehicles and the range of operation is wider. Therefore they can and do operate outside the range of many vehicles. My 99 Chevy pickup can not use Bosch O2s. They throw a code every time.

A good rule of thumb to follow is when you buy electrical components, stick with OEM. The crap available at auto parts stores is a waste of time. Even if they come with a lifetime warranty, it's not worth it. Especially the components that are hard to get to like fuel pumps and alternators. Who cares if you never have to pay for another one if you had to replace it 6 times. Oh yeah, don't forget the issue of trying to troubleshoot a problem with the engine and you keep saying to yourself, "that part can't be bad, I just replaced it with one from Autozone". Then after hours of elliminating other causes, you finally realize the crappy part that is new was the problem the whole time.

I'll get off my soap box now.

FYI, that is a great price on O2s (just ordered 2-$67.88 after shipping). Last time I got them I ordered through Sam Taylor for $37 each (which was far better than the $71 most dealers charge ).

 

That is a good price. Thanks to Dave for the link.

 

Great price, I just ordered 2 myself. figure its worth it while im doing headers and mine are original. Can't go wrong there for that price.
Thanks for the link
