Nubira II from Budapest (English)

My recent calculation after 254km resulted in a mixed consumption of 8.66%, since I drove in some cities as well.

Some updated:

- I went to a muffler shop and the guy who inspected it showed me underneath what he found. While showing me the rotted part, and scraping the rust off the pipe with a screwdriver, he poked a hole into the pipe 😄 It was going to rust through soon anyway, so I'll take it back to replace the pipe and middle muffler on Monday. 

 

- I also bought a new front grille which will be replaced when the hood is going to be repainted - hopefully this fall. I got a new leather gear shift boot which was advertised as correct size for this model. It's not. Even when I cut some of the sewing and rubber on the skirt's bottom, I couldn't drag it onto the frame. I guess I'll have to take it to a car upholstery shop maybe they can do something with it, or make a new skirt themsleves. On the picture the left one is the old one, it's ruptured. 

Also we made it to 280 600 km, nice round number 🙂 

On the week after the next week I'll finally take it to a mechanic to check the ignition coils, fuel pressure and if thoes aer fine, then I think it will be the injectors.

Salutare! 

The exhaust pipe with the middle muffler has been replaced with thick metal that was protected. He ordered one from a muffler wholesaler, but the folding was leaking on the middle muffler, so the guy made it himself. Anyway, it looks nice. 

 

I took the car back from the mechanic yesterday. He said he didn't find anything wrong with the ignition, or the engine itself. The muffler puffing can be caused by either the injectors (injecting extra gas sometimes), or the catalytic converter, which sounds like it's empty. Other than the -becoming worse and worse- valve lifter sound, they didn't hear anything suspicous, and said that she drove "wonderfully" on the test drive. They replaced a coolant hose, and a crankcase vent tube because they were badly cracked (they showed them to me, I just didn't take pictures). Also he said that both the engine and transmission mounts are gone, but I will replace them later, as they don't cause heavy shaking, and both of them are quite expensive here 😭. (Together around 770 Leis converted to RON.) 

So next up is a catalytic converter replacement. And still want to arrange the upholsterer to make the shifter lever boot.

Don't you have somebody with a Scan-100 GM tester to check your car out?

I do, they said there's not any codes, and everything's fine. Although finding someone with a Scan-100 is quite hard nowadays (at least where I live).

Little update: ignition coil was replace. Spark plugs from cylinder 2 and 3 looked nice, but the plugs from 1 and 4 were much worse. The guy who checked it said that spark plugs 2 and 3 are ignited at once, and 1 and 4 again at once. So he thought the ignition coil was bad, and replaced to another used original GM part, since we couldn't find a new original GM one. The catalytic converter was also replaced to a new one, since it was toast due to bad ignition. (In the picture they are in order; 1-2-3-4)

After the replacement of the cat, the car started to have a new problem. At first, it wouldn't go above 4000 rpm in any gear. I could feel she was able to go above it, but something did not let her, so she started stuttering but not go above 4000. Then it turned into a temporary problem, meaning if she was in the mood, she could go well over 4000, but other times it disables going faster. 

Today morning I visited a friend who has Scan-100. There was no code whatsoever, and every value was perfect, except one. The O2 sensor was totally wrong, it jumped from lean to right all the time, and the values it gave were incomprehensible. The diagnosis was that due to the bad cat (melted insides) and the replacement of it (the pounding which came with it), the O2 sensor was comprimised with metal catalysts dust from the old cat. If I'm lucky it will burn off after a few hunderd kilometers. If not, I'm in for an O2 sensor replacement, wich isn't that bad.

In other news, the steering wheel was reupholstered with leather, and the steering coloumn was replaced to a newer version, which is tiltable. The one the car had originally was just straight. Since the screws of the ignition switches had to be pierced, it took some wizarding to replace the steering coloumn keeping the original ignition switch, but it worked.

Just checking in. The "sometimes it doesn't go above 4400 rpm issue" still exists, when I took her to the car elecrtician and they took her for a test drive she didn't produce the problem, of course... It is the only problem right now, so I'm not mad. 

I forgot to show you a brossure I found online, of course I bought it. It's full of stereotypical marketing sh*t, and some grammatical errors too 😄 Lots of typos and some left-out words, it's funny how they released that brossure like that. 

 

Currently I'm trying to find a 30 (or 32?) mm diameter flexible tube that has seen better days on my engine. I cannot find it anywhere. I asked in the Hungarian Daewoo club and someone said it isn't even possiible to replace it without disassembling the A/C system. Is there something I can replace this tube?

 

 

And lastly something interesting. I just came across an article about an early Daewoo concept car, the Bucrane. Did you know about it? I really like the look of it, it's a shame it never got into production. Link:

Well, you could replace that entire AC pipe. It's not that complicated. Just recover the freon, take a few bolts and that's kind of it. The part number is: 96269572

It's number 4 in the picture:
