Been having issues with this car of late. Changed the rotors, distributor caps, spark plug wires (plugs were changed recently as well but not at the same time), and two coil packs. And also the O2 sensors. Car was burning too rich, hesitant up hills, poor MPG. After all of the aforementioned changes the car ran almost 100% for first couple of weeks.
I also changed the O2 sensors with aftermarket parts but think I may have wired them up wrong. The original sensors have two black wires, a white and a blue. The aftermarket has two white, a black and a gray. Might have been stupid but I connected the two black wires with the two white wires (made sense since there were two of each but maybe I'm doofy like that), the black with the white and the blue with the gray.
Didn't get any config with the new sensors. Any advice or opinions would be greatly appreciated!
Got a message back from the seller: Output wire is the black wire. White are heater wires. Ground is usually gray. I think I did right then with the white on black wires (2)...according to Stack Exchange. So maybe I just made an error with the black to blue and gray to white?
If someone has done this recently and remembers how they solved this, please holler!

But heres what I found.

Try Rock Auto for OEM brand Denso O2 sensors offering correct connectors (no splicing)
Probably they sell for close to the same price you paid for random aftermarket stuff.

Lose the splice job.
X2, I would not bother with the splice deal either. And butt connectors are not good around road wash and salt or what ever else gets in there to cause problems.
Never had any issues with the universal Denso sensors i've used ,splice right up without issue and wiring even matches factory as denso made the OEM sensors.
Get a proper diagnosis if you can't do it. You've already wasted lots of money throwing parts at it. That's NEVER the way to fix a concern. If you can't diagnose it, take it to someone who can. If you want to change the part(s) that's diagnosed then fine.

Yes, I've never had problems myself with universal ones.
True, it's easier to screw up if you screw things up. But if you don't, each wire is just a wire. So for anyone out there who has never tried it, but is usually successful in fixing things, you should not be worried about this one.
In addition to the sometimes significant price savings, the universal ones are often easier to find.

Well, you can look at it that way or that it's part of a major tune-up that was needed, right?
