It's from not cleaning the injection valves... The garage who fixed the engine of my old 633CSi highly recommended to do a supersonic cleaning "pretty soon". I thought there's no need to hurry. 6 weeks later the engine was f.cked because of bad injection characteristics (like I described above.) I still could beat myself for not doing it. :aua:

Oh my good.
is that from using liquid cleaner ?

There are no short cuts i gues here either, i will absolutly do it right.

I paid for not doing it in the right way...

Hi Schnarri
I kind of had that fear about the liquide cleaning, but there could be one that have tryed a great product. I suspect that it is going to cost to have them removed and cleaned, might be cheaper to bay new maybe. What did you pay for that operation ?

You could add a valve cleaner fluid to the fuel. But using a cvleaning fluid does not have only benefits... the particles detached by the fluid usually get burned and/or exhausted. But it also may be possible that single particles either may block up the nozzle or -much worse- change the charakteristic of injection so that the fuel will be injected into the cylinder more like a stream instead of a spray. Causing heavy engine damage, believe me...
I know that a cleaning by supersonic won't be cheap but it's worth. The cleaning will be much more effective!

Hi i think we located the problems in Lübeck, well it lasted two days to find out what it was, first thay made it worse then thay got it to drive almost okay. But the main problem are sparkplug cabler (dont know if its the right word but i hope you know what i mean), secondly thay mistake that the fuel injection ventils needs to get cleaned.

Dos anyone know if trere are a shortcut for cleaning them, without taking them all out and cleans them electronicly, thay said was posible, is there any other way, to do it safe ?

Ahh great i can write in englisch, i can speek german but i have big problems writing german specialy in tecnical matters, but hay might be funny to se where an babelfish dialog will get us :-)
My B12 i 10 numbers earlier nr. 67, nr. 70 lives in the same city as i so the babies are going to se eachother offen :-)

I have desidet to go to Lübeck Thursday to get Autohaus look it over to be sure and have som equipment on the car.

But anyway the problem is that i kind of sets out normaly it runs fantastic the first 5 minuts from start then i comes it is very little when you drive normaly no acceleration, and it is here you have to Kill you radio to hear it :-).
But when you accelerate it very clear it shakes under acceleration until 4500 rpm and then it pulls smooth, it is no running smooth in standing in P either, i have talked to mr. puscher and LMM are unde suspision aswell as lamda, we just messurede co2 in the weekend and there are no difference between the exhaust pipes, thay are the same. but it seams like the mix needed more fuel it was alittle low, this whare cold when we messured it so the kat should not work. That didn´t tel me anything but maybe some of you. ofsourse fals air and the throttle valv and fuel filter is on the list. I have borrowed LMM from another car that should run well but thay are old to, but somting happend to the better not mutch but it got better under normal driving and i had a trip at 50 km whar there whar no problem, but when i drow home we whare back bur still better than the original LMM.
Hope someone have tryed somthing simular or just know what coarsing it.

Hope to hear somthing :-)

Hallo Michael

Willkommen im Forum! Eine Vorstellung deiner Person mit zugehörigem Baby (E31) als Foto im Bereich Mitgliedervorstellung wäre noch nett.

Zu deinem Problem:
Wenn die Zündverteiler in Ordnung sind, würde ich als nächstes die Zündkerzen kontrollieren. Natürlich auch die dazugehörigen Zündkabel.

Schön, daß du dir die Mühe mit dem Übersetzen gegeben hast. Babelfish hat da ja wieder was sehr imposantes geschaffen. Die Übersetzung des Bereichs: "Sie müssen den Radio töten" gefällt mir sehr gut :lachen1: .
Means: "You have to murder your radio"

Andere wissen warscheinlich mehr als ich.

Hallo bin ich an diesem Forum neu.
Dort bin eine Menge Themen, durch zu schauen, also nehme ich die Wahrscheinlichkeit, daß sie nicht die die meisten empfiehlt Problem, Hoffnung des es nicht ist.
Ich erhielt mein Traumauto E31 B12 5.0 coupe, für einen niedrigen Preis, wissend daß es einige Probleme mit ihm gibt, aber er hoffnungsvoll wird in meiner Garage für immer bleiben. Das Problem ist, daß es unter Acceleration hakken, es accelerit aber wie wro..oo...oo..oo..oooommm (weis nicht, wenn Sie das erhalten)? aber irgendwie, nachdem 4500 U/min es glattes laufen läßt, konnten einige gerechten Aufenthalt über 4500 U/min sagen, aber...! Wenn Sie normalerweise auf Autobahn stetig herum 120 km/h laufen lassen, die sie fast glattes laufen läßt, aber Sie ruhig es hören können darlegen, Sie müssen den Radio töten und wirshlisch hören aber, es tut es noch. Ich habe mich des Misstrauens habe gesprochen mit Mr. Puscher auch, aber ich wollte von Ihnen hören, wenn Sie meine Strategie bestätigen. Ich habe

LMM von einem Freund mit einem alten E32 geborgt, das es die gleiche Teilnummer war, und das änderte etwas, erhielt es wenig besser, aber dieses Auto ist auch nicht neu. Ich habe Funkenstecker zu geändert.

Konnte nett sein. Ihre Ideen auf diesem, Dank im voraus zu hören?

By the way, can i right in english in the german forum, not well in german, take alot of time through translation on babalfisch ?
