I'll give you a hint. They are "hiding" somewhere in this area...




But maybe you should put down the socket wrench/adjustable wrench and back away slowly.

Also, your belts look pretty cracked and due for a change.

Add it to the ever-growing list.

great thanks! i will get the kit from z1 (once i take care of suspension)

it includes

hopefully that will cover everything. is there anything to worry about with the black soot here?





I hope i win this 2023 z with all this money im spending at z1 lol

Edit:****. One day at the 6 mile commute place I make more per hour at, and they sent me back to the 30 mile (originally thought 25), one way commute to make less money..

Anyways, what are your thoughts on this? Maybe soon after the trans install and all, partially doing suspension. Its messed up bad, and I may be able to schedule to have this done somewhere, without having to rent a car. I was thinking

1. ball joints
2.compression rod bushings
3. front lower control arm/ shock bushings.


Then tackle the adjustable arms and specialty alignment weeks later. Does that sound like a bad idea? Something has to be fixed soon with the suspension, and i wont be affording all of it very quickly. Almost got the trans loan behind me!

Since you're paying someone else to do the work, I would do the bushings and FUCAs with the final alignment all at the same time so you're not paying for labor twice.

Cool. I may just wait then and hope it doesnt break, or permanently mess anything up before im ready.

As far as running catless test pipes, some of them will have an elongated J-shaped hook where the O2 sensor is mounted. This is meant to fool or trick the sensor in order to avoid causing an SES light. If your test pipes don't have this, search for O2 sensor anti-fouler or spacer in order to get one. They may work. They may not.

Or just get some HFCs and be a better steward of the planet.

I do care for the planet. Some fools were telling me its not better. They said the metals and chemicals used to make cats are bad, plus it goes into water supply out exhaust still. Im not sure though, it would suck to be like china wearing masks.

I did not see mention of the j shaped hook. theres some pics of the tomei one i got.

if i did split up the suspension work and do some bushings first, i would not plan on doing specialty alignment yet. I would hope to get by with no alignment or a regular one. Still may save and do it all at once

ha... there are several debates, i usually run 50-60% ethanol..but they say that because of cultivation and processing it is actually worse. i am no tree hugger, so it is what it is
https://www.axios.com/local/des-moin...-change-report
  • The five-year study, partially funded by the National Wildlife Federation and U.S. Department of Energy, found that ethanol is at least 24% more carbon-intensive than gasoline, Reuters reports.

What "specialty alignment" is this? A "standard" alignment with adjustable FUCA, camber arms, offset bushing, etc. is to bring the car back into spec. If the shop has to tear down everything (they do) to do the bushings, you will need an alignment no matter what. If all they can do at that point is correct toe (because no adjustable stuff), it's money wasted because even if toe is corrected, you'll likely have caster/camber issues. Just do it all at one time.

That's probably my fault, Mic. I told OP he needed to go to a dedicated alignment shop who specializes in this type of thing since your normal "toe and go" chain shop isn't going to take the time to unmount the FUCAs and get everything sorted. My opinion still remains to do everything suspension all at once.

Or maybe I used the word "specialty" because I think OP is "special."

OK, forgetting about the planet for a second...

Someone needs to explain to me how an electronically controlled car can even function PROPERLY with test pipes (no CH, CO, etc. reduction) when the typical ECM is looking for a DELTA between up and downstream sensors to properly modify AF mix for maximized performance and emissions kept in check.

In the case of test pipes, the upstream and downstream sensors will read exactly (or near exactly) the same since there's no catalyst in between to reduce the emissions. In this case, I'd tend to believe that when the ECM receives near identical readings up and downstream, it will cause the engine to alter the AFR in an improper amount trying to maximize AFR; thereby creating an issue with maximized running and emissions. Yes, one can tune the ECM to cause different readings, I know that, but without a tune, how can an engine even do its job properly?

This is a serious question that I've not been able to get a real answer to. I already understand exhaust theory, e.g., pulses, restrictions, flow rates, back pressure and all of that but test pipes on an un-tuned car eludes me only due to the O2 sensor readings and not how they function. Anyone offer me some facts on how these can work without a tune?

Or is it just folly to install them without tuning? (My take at this point.)

ok. I am leaning forward to doing it at one time now. The only reason i would split it up, is there is only one good shop i know of that does specialty alignments (adjustable control arms). They are good, extra expensive because they have a monopoly here, and slow (they like to take extra time while all these cool cars sit out there).

If i did split it up, i would be replacing just a few problem bushings or ball joints, since it is in bad shape. That way i could take it to my fast shop that does good work, but does not specialize in that. I would not be getting any adjustable arms and it would still be out of spec. I would get a "regular" alignment if anything. Soon after when i saved for adjustable arms and other suspension goodies, hopefully they could do it quicker and cheaper being less work. Also hopefully the work i do first will help the car not clang on bumps and hurt itself. Just an idea, i will probably ride like this carefully even longer, and try to do it at once.

If i am special heeltilidie, it may have to do with being indecisive. my ex gfs hate me for that, like trying to choose a restaurant to eat at..

also i would love to hear the answer to your test pipes question micvelo. I kind of dont want to hear the answer though. test pipes going on next week, and tune wasnt going to be for months..

buying sensor faker now, edit:
anyone want to link me to that? i found one, and it looks similar to the things sticking off my tomei test pipes lol. theyre expensive pipes, you sure they arent built in? heres the one i found on net

https://www.enjukuracing.com/products/vibrant-performance-saddle-style-weld-on-oxygen-sensor-bung.html

i didnt see the exact j tube, saw a u-j tube

The secondary sensor's ONLY purpose to to check that the cat is working effectively. It has no affect on the tuning or how the ECM controls fueling. Fuel injected cars before OBD2 only had one O2 sensor.

I don't necessarily care about the impact to the planet, put smelling fumes every time I drive is a hell no for me.

should be a plug that goes in the top one.. O2 sensor in bottom one... unless you have the bungs, you will throw a code

If the bung goes in the hole, is it a bunghole?

Thanks, A! I suppose I could have found that on the know-all Goofle but never thought about because the lead tech in my shop a while back explained it (wrong, apparently) all to me so I never thought to check (the belief set was strong). Ha! I did just go do a Goog and found some "semi-conflicting" info that sort of said it like I believed it. But, for the most part, it's as you described it. Thanks! I feel a little smarter now that someone has done a BRS reset on my brain!

Hmmm, now I'm wondering if any other parts of my belief set need challenging. Guess I'll be fact checking everything now. Like I'm not already borderline OCD...
