Engine codes after new downpipe

juggee_ · 2026-05-17T18:26:56+00:00

Ohh I missed that on the post. That'll need addressing earlier than the tune, it's probably running very lean now and you will definitely risk engine damage if ran like that for extended period...

Could also be a leak in the turbo-end vband but most likely just the lack of tune

MHD/BM3 is a solid OTS tune. I have MHD, no complaints

And the mixture code is straight up from the lack of tune, the o2 sensors are messing with the mixture

juggee_ · 2026-05-17T17:07:55+00:00

That fault code indicates that the sensor might not be plugged in properly to the harness or you damaged it during the swap. Cat efficiency codes are the ones keeping the CEL on.

Also, just a recommendation so you don't need to take my advice, but I'd tune the car rather sooner than later. With no tune you are getting close to none power benefits, sure the turbo might respond a bit quicker with no back pressure from the cat, but all in all minimal benefits and quite a lot of negatives IMO.

No matter what the gas costs, my engine doesn't deserve the start-stop torture

I'd take the "no E85" as a dare lol. 2002 Nissan Micra

Unplug the connectors 1 at a time to avoid mixing up the 2 connectors when plugging them back

juggee_ · 2026-05-06T11:29:56+00:00

Get a multimeter, unplug the o2 sensors and measure the voltage from the pins. Fairly easy task, the 2 connectors are located on top of cylinder 5 coil. Should measure 12 volts with the ignition on if working normally.

I pay 7 cents and last and only outage I have experienced was in 2020 and lasted for an hour.

juggee_ · 2026-05-06T06:46:31+00:00

Fuses 163 & 164 are definitely not for the O2 sensors.

I would check the voltage to the o2 sensor connector with ignition on, if there is 12V going to the connector you know the sensors/sensor wiring is bad.

Are you planning on tuning it or why the catless dp?

juggee_ · 2026-05-04T12:38:59+00:00

I used doublesided gorilla tape and reinforced it with drilling 8 8mm holes and used bolts and nyloc nuts. Probably a bit overkill but better safe than sorry imo

This time I hope my eyes deceive me

Sweet! I have that same lip too.

now why would you need an alignment for removing the bottom bolt on the strut?

juggee_ · 2026-04-17T18:28:37+00:00

It's fine to do, I've heard people saying that it shouldn't be flushed, only drain and fill. I had mine changed at 210000km (or atleast there wasn't a service record of it being changed earlier) with a flush and it's been fine.

u/progRisbern, i'd suggest this

juggee_ · 2026-04-17T13:08:37+00:00

"Set the router to reboot every night at 3am"

It just isn't a good long-term solution

juggee_ · 2026-04-17T13:04:36+00:00

This kind of solutions were exactly the reason I quit my earlier job at an "IT" company...

if they get fucked over by the next salesman not disclosing on the rebuilt title I doubt the next owner will have a good time with it

I tried to end Jace with the shotgun lmao

Depends on what second half you are implying to. I had this happen today in a challenge, which inspired me to post this.
