Guess what?

I guess I've been a bit confusing, so let me clear things up.

I have been having TWO problems.

1) The car has a slight misfire that can be heard and idle and low rpm's.
2) I kept getting a CEL on 1/4 with the code 1212 (multiplicative value for self-adaptation lambda regulation, and or, additive value for self-adaptation lambda regulation). Yeah I know, "which one?".

So.

My thinking is that the miss was the cause of the light. Which is when I started swapping out parts, O2 sensors, coolant temp sensors, spark plugs, crank sensors, injection rail connector harnesses, and the last injectors.

Now Dave I know you are thinking how can your kit help, but not help???? Since I had replaced everything that I could think of, and the miss was still there, I figured it had to be a wiring problem. Which is where Eric's fuel rail loom with your kit comes in. Well Eric was kind enough to lend me his injector looms so I could test them on my car. Before I swapped the looms, the popping from the miss could be distinctly heard at idle. Well After I put Eric's rail loom in the popping went down to, best I can describe, puffing. Not as loud but still there. So that is why I said it helped, but didn't get rid of the miss. It also let me know that my injector loom nor Eric's was the cause of the low rpm misfire.

Is the "smoke" clearing the room????

Now on to the 1212 code.

This past weekend I was thinking about how much I like my exhaust system that Ozzy made for me, and how I want to get this stupid miss cleared up so I could drive my car again. While I was thinking about this I remembered seeing little bits of white glass packing coming out the exhaust a couple days after I put his setup on. Not a whole lot mind you, and not the first day, it was a couple days later I noticed it what look like little white hairs getting blow out and a couple of feathery looking bits. I just chalked it up as left over packing getting spit out from when Ozzy welded it up. That was until I called Ozzy and talked to him about it. It was not until then that my problem emerged. Ozzy didn't use white packing his is GRAY, and mine was WHITE, which is the color of the packing under the heat shield around the factory HEADERS!

Well son of a two balled beeotch!

So I suspect what is happening is that the heat packing from the headers is getting sucked through the exhaust and spit out the back. I'm guessing It didn't get out before because I had the stock twin can mufflers on my car, and maybe the packing was getting trapped in the chambers of the cans. Being that there are two cans, little to nothing would come out. But since Ozzy's exhaust flow WAAAAY better than stock, and because I'm running highflow cats, the fibers get sucked in and spit out straight away.

Which leans towards the 1212 code. Since the headers are "leaking" not only are they sucking in glass packing they are sucking in more AIR, so no WONDER the O2 sensor can't adjust the fuel mixture. The sensor is seeing extra oxygen in the exhaust, so it adjusts the fuel to richen it up. Now I don't know if the Motronic does this for all the injectors on that bank, I'm guessing it does, saying it does then that would make some/all of the cylinders too rich. So the Motronic is going nuts TRYING to get the mixture correct, richening it up, then leaning it out, rich, lean, rich, lean, and can't because of the "hole/s" in the header down stream.

"Smoke" still clearing the room?

Now I haven't ever heard of a 348 header melting, be we know good and well it's a problem on 355's. I see no reason to doubt I have been dealt a bad hand with my header/s.

So..........it's of to the header shop. But then I still have that low rpm misfire to deal with.

Given lemons - make lemonade. I wish. I have been given a lemon TREE, and think I may be out of sugar!

 

Hahahaha!!!!

I love it!

You HAVE to make that your avatar Rick!

 

After.

I have been talking about it for a few years, but now I have to.

 

Yup. This is in the plans.

But I'm gonna go one even better. Not only will Dave's kit be put in but I am SERIOUSLY considering rewiring the entire loom with Mil-Spec wiring.

However, since these damn headers have had it, that now goes back on the shelf until I get the headers made. I could do everything all at once, but then if the problem goes away I wouldn't be able to pin point exactly what the problem was. So it's the long road I guess.

 

LOL!!!

 

Well I guess this means I'm just gonna have to pull the headers and see for SURE what the deal is.

 

I welcome any and all ideas. Because this chump is stumped.

Matter of fact why don't you spark up that 12 cylinder of yours and drive it up here tomorrow to give me a hand removing the headers for a looksy inside.

Whatcha say fatboy?

 

LOL!

Wiseass.

 

Good point Dave.

Man this just sucks sweaty donkey balls. I really wish this pile of crap car would just stop giving me grief. It seems as though soon as one thing gets fixed another pops up, and then another, and another, and another, and..............yeah another, and another after that. Be VERY careful what you wish for. When I first bought this thing I wanted to learn how to work on it myself, and BOOOOOOOOOOOY did I ever get a lesson.
