Sr20det bogs when o2 sensor plugged in

[Ljensen11]

I just got my swap done and I have been running without a o2 sensor for about a week and it runs fine no problem got the o2 sensor and plug it in and when i went for a ride and it bogs under acceleration and when I unplug it it runs fine anyone I know my problem?

Either mismatch O2 sensor with ECU or wired wrong.

If you have a redtop you need the skinny (87 280zx turbo) oxygen sensor. If you have a blacktop you need the fat oxygen sensor. Maybe the wires for yours got damaged during install otherwise. If you have an aftermarket ecu you may need a different 02 I dunno.

S13 SR20DET Skinny O2: 22690-50F00
S13 SR20DET Fat O2: 22690-50F02

They say the '87 300ZX Turbo oxygen sensor works, but there is a different part number for it: 22690-21P11. So who knows.

[Twiglet240]

Those parts numbers for the skinny o2 are different in the sr20det faq.

S13 sr20det redtop: 22690-19p20 ('87 280zx)

I just ordered this one for my car so I hope its not wrong lol.

So did it work?

I think I need a skinny o2 sensor for my redtop SR, because I have a fat o2 sensor on it right now and my gas mileage is around 23mpg babying it and mostly highway.

RockAuto.com shows this for a 1987 300zx turbo

Then they show this for a 1987 300zx nonturbo

Looks like the nonturbo one has the correct plug on it (oval, not square). Anybody know if that'll work?

[OutlawLui]

the bottom plug is the correct one, but the o2 has to be skinny. Just buy the correct 1 from frsport

FRsport wants $100 + shipping for theirs. If I can get a z31 o2 sensor on RockAuto for $22 and it work exactly the same, then I'd much rather do that.

Hell, the Standard Motor Products SG130 sensor that RockAuto sells for the z31 is on ebay for $18 shipped!

Let me know if it works for you. My Red Top came with the mismatched fat 02 sensor also. and i just bought a used Skinny Titania 02 for $20. Don't forget you need an adapter too

[cbh148]

Yeah I'll let you know if I end up buying it and it works. Do SR's have a mode on the ECU that I can switch to to monitor the o2 sensor switching? I know my CA18 did.

Anybody have any insight on whether this 1986 300zx o2 sensor will work for a redtop SR? I'm thinking that as long as it's a skinny o2 (which I assume means it's titania like it should be?), and has the right plug (oval), then it should be what I need. Thoughts?

[sleepyS14se]

this is semi off topic but on my ka24 i need the adapter as well..

my head has the typical m18 size hole for a standard sized o2. my downstream o2 is the skinny kind and obviously i need to adapt.

anyone know what adapter is needed and where can it be purchased from.
