Guess I'll start by unplugging the secondary sensors and see if that makes any change.

If it doesn't, I guess one of the main sensors has been damaged and will have to be replaced.. yippie..

Have you tried cutting out random harnesses? I hear it's great.

Blah blah blah...lame car/race car.

Could be a damaged wire run to one of those sensors, too. Could check that with a meter on the connectors and the wiring diagrams for the sensors in the EC section of the manual. But yeah, if that doesn't work, just cut more wires till the car stops bitching

It's possible, but those harnesses ride inside the one that runs down the side of the tranny, so I don't have any reason to think they'd be damaged like the main O2 sensor (drivers side) was from the heat.

Still kicking myself for letting that happen, but I repaired the harness... I just hope it didn't do something to that sensor that's making it blow the fuses.

As a diagnostic step I'm going to disconnect the secondary sensors and do a drive cycle, see if it pops the fuse. If it does not, I will do a few more cycles until I am satisfied and then figure out where to get some O2 bung plugs.

If that does not make any difference, I'll have to sit down with my multimeter and the main sensors and see if I can find a high impedance conductor or something. Sigh.

If its the secondaries causing the problem, and you're running UpRev you can disable them completely and keep them removed, as long as you don't need to pass inspection(it will show as "Not Supported" for heated catalyst).

Hans, yeah that would be the plan. Hopefully that's all I need to do, really don't want to pay for a new primary O2.

Where can I disable the sensors within the software?

wstar · 11-04-2013, 09:16 PM

I think you just remove the sensors (if you have something else to plug the holes with) and disable the CELs for the malfunctioning heaters + sensors in the long list of disable-able CELs. Never tried it myself, though.

Sh0velMan · 12-05-2013, 10:55 AM

So I put a 30a fuse in and it hasn't popped.

I'm bad, I know. I just hate trying to nail down electrical issues with no obvious cause.

Other than that, I am more or less hunkered down for the incoming baby, so I haven't been doing anything with the car. I have an annoying rattle just behind the drivers' side seat that I can't identify. Can only reproduce it while the car is in motion, seems to be caused by an up and down motion of the car itself... So if I have free time in the coming weeks, I'll probably be out in the garage with a mallet trying to isolate what is rattling.

Yippie!

Mike · 12-05-2013, 08:41 PM

you can actually hear a rattle? Mine is so loud without an interior and with the open exhaust that I'd never hear a rattle.

synolimit · 12-09-2013, 08:32 AM

My gas tank covers rattle. I just reach back and punch them.

DEpointfive0 · 12-09-2013, 10:49 AM

If you need a primary O2, PM me

Masterbeatty · 12-11-2013, 05:39 PM

How do you like the stance coilovers since they have been on your car for awhile now? Im about to get the stance pro comp 2's with the swift springs. How have they survived the spirited driving?

Don't think they make those for the Z34, but either way...

The coilovers are great for the money and have held up fine to the one autocross and ~200 street miles I've been able to put on them.

I can't really speak to their long term durability, however, Spohn has put hundreds of track miles on his set and swears by them.

Best true type rear coilover for the money by far, I think.

Masterbeatty · 12-12-2013, 06:12 PM

I called them up. They do make them but it's make to order and said it would take 4-6 weeks. I just am interested In Build quality and durability. But if there are a few people here with them and happy then I think I'm going to go for it. I guess they also have an option for swift springs as well so I might go that route. Thanks for the info though.

Sh0velMan · 03-28-2014, 10:53 AM

Spent 3 hours working on the dash wiring harness.

Not even close to half way done.

What a mess!
