Idle Stuttering.. golf II 1.8 monojet (english)

[Trennschleifer27600]

hey guys.. sorry for intruding your forum!. please answer in english as i don't know a single german word 🙂

anyways.. i got some problems with my golf.. the idle is stuttering like mad.. the only thing i could think of is the lambda probe.. but that was changed 3 months ago 🙁

anyways.. i got some vids for you to see/and hear how she runs on idle

vid 1
vid 2

in addition to having the lambda probe changed, i've changed the following bits

blue/red/black temp sensor
distributorcap and rotor,
all spark cables
coil
sparkplugs
lambda probe

and its still stuttering and causing problems to me.. the car shakes like crazy!

and i've head that its possible to read out failcodes from the car. where is that done, and how, and what are the codes (where can i find them)

The car in question is a:
VW golf 1991 1.8GL (RP - monojet)

Regards from your pals in the north (norway)

Hi Housey,

i do not relent :-) you can simply check the vacuum line from the brake servo, dismount the rubber hose from the connect to the Bridge and close the connection with your finger or something different. The procedure takes only 5 seconds and then we are sure that there is another problem. The Lambda probe would show you, if it was defective, another cause. The idle would be nevertheless clean !

well.. gonna try that this weekend... after i've picked up my new GTI rear axel 🙂

so, if i try to blend the line with my finger or something else that will make it a tight seal.. then i'll be able to see if that actually is my problem?

harr.... this would have been 9000 times easier if i had a pierburg 2e2 carb.. those i know in and out.. this monojet thing is hard to understand 🙁

but i'll keep on trying.. looks to me like i should go out i buy a few meter of vakuum hoses and change all the vakuum lines in my car.. just to have done it

YES !!! :-)

You put your finger on the line and/or blend the connecting piece at the Engine (Sucking in Bridge) where the rubber hose is normally connected. Then you can be sure that there is not an error.

That would be probably best for the future :-)

Then we will see ...

@ Ringfuchs

You must really love your lambda probe 😁
(Dinge die man eigentlich in der dritten Pers. Sing. benutzt mit "she" zu bezeichnen macht man bei besonders liebgewonnen Dingen. Bspw. dem eigenen Auto. Achtung, manche Dinge haben auch im englischen ein Geschlecht, obwohl sie eigentlich Dinge sind. Bspw. der Mond und die Sonne, wobei im engl. Die Sonne männlich und der Mond weiblich ist!
Demzufolge musst du eine sehr innige Beziehung zu deiner Lambdasonde haben 😁😁)

@ Housey

What what what whaaaat? 😰
To me, the Monojet is quite simple compared to the 2E2. It works way striaghter. But, I have to admit, that in case of malfunktions it's quite complex to find the part beeing responsible for the error. Also, I've never been familiar with that thing because i think it is inferior, compared with a good carb or a multipoint injection.
Also i do like you, just because you like the 2E2 😁

Das ist nicht richtig. Eine defekte Lambda kann sich extrem negativ auf den Leerlauf auswirken.🙂

(That is not correct. A defective Lambda could affected the idle extremely negatively.)

its the other way around for me.. i know the 2E2 way better then the monojet..

i'm not too good with electronics as you can see.. but i'm learning.. i've had 2 golfs which used the 2E2 carb.. so i've rebuilt a few of them.. i'm just new to the monojet thingy...

and soon, its gonna be k-jetronic for me.. but i really would like to fix this problem before then... since the engine in my car is going in another golf after i've converted into 16v 🙂

Das wäre mir beim RP neu, bei einer defekten Lambdasonde hat man entweder Lambda 0 oder Lambda 1, der magere bzw fettere Motorlauf hat sich bei meinem RP damals nur durch Leistungsmangel durch den fetten Motorlauf oder im Gegensatz stottern bei höheren Drehzahlen (mager) bemerkbar gemacht. Der Leerlauf war in beiden Fällen völlig normal ... wie es aussieht wenn die Lambda kurzgeschlossen ist, kann ich nicht sagen

Bei Housey denke ich eher an ein Unterdruckproblem, da es typisch ist für den stotternden Leerlauf und der Motor ja sonst gut läuft

ehh?

He thinks the error is caused by the vacuum system.
A Lambda =1 or 0 caused on his car only problems at full speed, not on idle

starting to suspekt that myself... gonna try out a few things this weekend.. will report as i try things 🙂

@ Gen.Golf.II Danke für das Übersetzen, habe ich nicht dran gedacht

Thanks for that translate

@ Housey We will see which result your test on weekend will show us

[Trennschleifer27600]

well.. i blended the hose. nothing happend.. so i think the problem lies in another place.. so i'm going to buy a few meters of vakuum hose, and change all the hoses that are there...

[norder]

You are on the wrong way ......

[Trennschleifer27600]

oh? am i ? tell me what i'm doing wrong? need all the help i can get!
