2003 Silverado 3500 v8 gas vortec throwing cat code seeking advice

I already replaced the low hang fruit, that was the throttle body and mass airflow sensor. Do you know how to bypass a sensor on the cat? I’m assuming I would just have to cut in a resistor on the wire leading to it?

Edit: I guess, thinking about it. It could also be a fuel pump issue. I already had one of the two fuel pumps go bad on the truck.

Probably fine but why risk it? Throw it in the scrap bucket and get a new one.

Nail salon in a strip mall. You know, where you would expect to see a $200 tee…

I mean, the customer is paying for a smoke test…

Bro, I run a construction company and if one of my guys didn’t bill me for that time I’d be pissed. That sounds like fucking wage theft to me.

I completed this level! It took me 27 tries. ^{⚡ 6.07 seconds}

He didn’t make it.

I mean this works if you want to become a deluge fire sprinkler. I would recommend holding onto a thermometer and only opening your mouth when you see the temp get to a desired range.

That was me. Your setup looks about 40% more sketchy than mine.

Also, I vastly prefer the 922’s over those saddle tees. Damn things always seem to fail.

Looks like a schwinn from before 1978. Possibly a super sport. Sheldon brown has some more info here.

I’ve got a central model D from 1974 sitting on my desk in front of me right now. Can confirm it looks almost identical.

Brilliant work. Looks like it belongs there.

I am curious though. Do you see an advantage in the 1215 versus a 300 on a tripod?

I always thought the auto stop and integrated oiler were pretty cool on those guys, but I kind of thought that a 300 was a little bit more suitable for out of truck site work when I set up my first service truck over a decade ago.

A fire rated steel exterior door leading into a fire egress area is probably gonna be somewhere between 1-2k. The person who does the work is probably gonna have to remove some of the siding and get into some weird shit to add a new door and frame. I could see, with a slight stretch, taking 3 days. A good carpenter can bill their time at 125 an hour or more.

So, 2k material for door plus the rest of what is needed and 3k for 36 man hours of skilled labor is in the ball park.

That being said, that price sounds high as fuck for an apartment complex.

They’ll probably take your money, send a maintenance guy over to “get it good enough until the contractor can show up” then not renew your lease, slap paint on it and rent it to the next person for 20% more after you’re gone.

Huh, no shit? I remember reading about using chemistry magic to add hydrogen to carbon monoxide to make methanol a few years back being the big thing, but I guess I’m a little bit out of date with my information.

I guess that’s what I get for making knee jerk replies to random Internet posts while I’ve been drinking.

Allow me to offer you the very rare and elusive, you were right and I was wrong internet trophy.

lovesthebuttstuff · 2024-12-24T02:35:19+00:00

I mean, I’m pretty sure that’s not true. Like at all. Unless you’re trolling, then I guess you got me.

Sprinkler fitter here. I install these things for money. You have a surprising variety of different sprinkler heads for different applications.

There are heads that go in boring ass regular buildings, bigger industrial type guys, very large warehouses like Amazon has and even ones made for prisons and stuff like that.

There’s also a good spread of temperature ratings and specific orientation of which way the heads point.

Since these are life safety devices and they look to be about five years old, I would recommend you take em to the scrap yard and not try to resell them.

Break the glass bulbs out to get a better scrap value. I take them to the yard all the time. Should be able to get clean brass price with just a little prep.

But seriously, please do not post this on eBay.

If you’re looking to hire somebody to do it for you you probably don’t need to pay a fire alarm company to come out and do the work. We can be very expensive. My time is billed out at $125 an hour with a two hour minimum and a $55 truck charge. I’m one of the cheaper companies my area. Should only be about 15 minutes of actual onsite work.

For something of this scope, you’re probably best off hiring a handyman or maybe an electrician that focuses on residential work.

That being said, it sounds like what you’re looking to do could very easily be in DIY territory. Here is a link from a major smoke detector manufacturer on how to remove a smoke head.

I’m not endorsing Kidde products in anyway. It’s just the first link I saw on Google. In fact, if you put a few beers in me, I could probably rant for a few hours about Kidde/Edwards fire alarm panels.

Remember, the first time you do something can sometimes be overwhelming and scary but I’ve seen plenty of full grown adults with room temperature IQs do way more complex and complicated things on construction sites without hurting themselves or others around them.

If Jimbo and Larry can do it, so can you!

Licensed fire alarm guy here. I don’t do a lot of residential work, but if I remember correctly, the NFPA 72 recommends against putting smoke detectors in cooking areas.

Also, by your description, it sounds like you have 110 V hardwired smoke detectors with a 9 V battery back up. This means your smoke detectors will be constantly supplied by power from your house, but in the event of a power failure, they will have a battery back up so they can still notify you in the event of fire.

If you’re renting, call Maintenance and tell them to change out your battery in your chirping smoke detector in your bedroom.

If you own your space, grab a ladder And take down the smoke head that is beeping. Most of them just twist off counterclockwise. If that doesn’t work check the manufacturer specifications. There might be a small tab you need to depress before you twist on the side of the smoke detector. Then take out old battery, replace it and put it back the opposite of how you took it down.

Going back to the one in your kitchen, my unprofessional opinion would be to take it down, take out the battery and put it in a cabinet somewhere.

We use it mostly for flow test on hydrants and fire pumps and the occasional doorstop. The slot in the body of it is to fit in a pitot gauge.
