Buenos días amigo yo tengo un mersedes Benz 1990. 420 SEL. Seapaga y vato para prender ke ago

My car is smelling petrol and not starting as you say

Hello Sir and thank you. I have a MB 190-E, 2.3, 1988. It takes about 2 minutes of constant cranking to start, regardless of hot or cold. I have replaced the cold start fuel injector and the fuel distributor by the carburetor and a new fuel pump and filter. Once it is running it is fine. I am going to try this and see if it works. This is something I never considered. I GREATLY appreciate what you make available and your obvious expertise. If you have any other suggestion I (and I beet many others) would love to know about them. Best regards, John

Hello from Cheshire UK, my M104 SL has been laid up for 7 years , i had to change both pumps the accumulator the filter, clean the small filter on the distributor AND then it started but so much black smoke, no idle and very lumpy any ideas would be most welcome, I use your videos to give me an overall idea of what i should be doing and looking for and how things work , I thank you very much for these videos, we are not alone with good people like you to guide us.

Incredibly useful, just bought a 230TE 124, i have a feeling I'll get a lot of use out of the information you share!
Thank you from all of the younger enthusiasts!

The plunger on my 230E kjet, is held in by a clip, which allows it to be withdrawn simply by bending the clip. The effect of this is that the plunger rests against the venturi mechanism and there is no freeplay. It starts no problem.

Thank you for this video! Does the 1,9mm also apply for adjusting the sensor plate in a K-Jetronic or only the KE-Jetronic?

Selamlar bizim garaj da w 123 var e 230 jetronik sisteme sahiptir benzin ponpasını ve filtresini değiştim benzin tankinın içindeki eski yakıtı temizledim tüm hortumlarıni yeniledim ve benzin ponpası çalışamadı benzin relay ini tamir etim ve araç çalıştı sonra söndü rolantide brakinca çalışıyor pedala basınca sönüyor ve benzin yemez ne olabilir

i am so appreciate you about thing and secrets no one tell us about it ,great engineer

Thanks!

So you have to push down to turn the screw? Idle mixture and sensor plate is same adjustment?

So we have to push down on the screw to make adjustments? It does nothing if you don’t push down?

Hello, first thanks a lot for your video. I just bought an audi 80 b4 with the NG 2.3E motor and she struggles a bit to start up no matter if cold or warm. Do you think I need to fine tune the CO screw ? Thanks !

Very applicable to the Volvo 240 Kjet Systems!
Thankyou for the video!

Hola profesor le mando este mensaje desde España quiero saber si puede hacer el favor de poner este vídeo en español muchas gracias

Hello from Greece, first I would like to thank you for your advices to fix our problems on our mercedes w201. I'd appreciate if you could tell me what's the right way to clean the ke jetronic system... For example can I use spray cleaner for throttle?? Thank you..

merci pour les vidéos Mercedes j'ai un gros soucis de pollution au control technique de la voiture ici en France la norme a ne pas dépasser est de 4.5% et ma Mercedes affiche 8.6% donc refuser car pollue

My screw doesnt do anything. Turned it clockwise even 30times and no difference

Thanks!

Hello From Australia. What is the Measurement for a Mercedes w126 500 se.........???????????

Bro, each guy needs a different woman

Great video! What if the jetronic is installed on the vehicle and you are trying to adjust it? Does it change the process? The vehicle is a 1987 SL560. Someone previously had messed with the adjustment and now I'm trying to get it in the correct position. The jetronic is installed with the air filter removed so we have direct access to it. When I use my calipers to measure the distance, like the way you show in your video, I measure 30.6 mm. The car runs but cannot hold its own idle (without pressing the accelerator) so we are thinking it could be a vacuum leak somewhere else. Previously, I made the adjustment rich and the measurement only went as low as 30.3 mm and wouldn't run too well so I started to lean it. Any thoughts or ideas?

Veliki pozdrav Ivica. Mogu li dobiti neki kontakt , E-mail ili broj mobitela da vam objasnim moj problem sa M103B26?

Hey, you probably have seen my other comments about my cold start issue and its now finally resolved, my sensor plate needed to be adjusted and then i calibrated my aftermarket potentiometer to 0.6volts and now its working perfect

Great video but I have tried to set it in my car but it sometimes suddenly stop the engine what could it be ??

I have a 1.8 m102. If i put a turbo on it, can i then adjust it clockwise to give more fuel? If turbo of course

How can you mesure 1,9mm? The scale on the meter is only per mm and not 1/10 mm. When you mesure the depth, you mention 27,8mm, but I only can read 28mm (2,8cm) on your meter. Is there a more precise manner to mesure the depth in tenth of a mm? Kind regards

Hi. I have a w124 with the m104 engine. It has a very high fuel economy, probably around 1,7 liters per 10 kilometers. I have checked the clerance and it is 1,2 mm. Do you have some tips to get the fuel economy down?

Thank you for the explanation! I currently own a 190e with m102 and I have access to a dynamometer. I noticed that my m102 is running lean above 4000rpm at wide open throtle, below 4000rpm and idling its fine and I got it to the AFR I wanted. But above 4000r it suddenly runs lean, what should I check on my k jet system ?

tres bon tuto , et cela fonctionne , ma voiture à retrouve les chevaux

Thank you for your informative video. It helped me understand the fuel injection system

Thank you so much.

Okay I did this adjustment but I pushed the Allen screw all the way down while turning it clockwise. The engine died when I turned it too far. It wouldn’t start after that so I went back to the original position I had it. So from your video it says don’t push the screw down while adjusting it, just turn it without pushing down?

hello ivica, my name is juan. for mercedes sl 500 r129 with injection that would also be 1.9mm adjustment.?

Does this apply to K Jetronic as well?

Excellent video 👍💗 thank you our friend

it is not cleer where 1,9mm was measured.From this side it was necessary to measure so that it was clear...

Bravo. God bless you for making this content which will help so many people. You have made things very easy.
