Hello!

becourse im not so good at writing swedish i do it in english, you can awnser in swedish!

for 3 months ago i bought myself a golf 2 1,8i

when i bought the car, the motor went already up and down a bit in the revs. doesnt stay stable on 800rpm,
when the motor is cold, it hangs nicely around a 1000rpm, no strange shakings in the engine or anything.
now when the enging is hot the rpms are uneven.
also a problem i have now, when im driving somethimes the engin starts to be really shaky, feels like its only going on 3 cilinders instead of 4.
pushing in the clutch and push in the gas the rmp goes up like it should, let the clutch come up again and i have no power, plus the car starts to shake in the accelaration.

now i changed for 150km ago the rotos, distributor head and the sparkplugs. the pwoblem was gone!
but now when i drove back from work yesterday, i had the same problem again!

does anybody knows what the problem can be?

hope to hear from you.

Börja med att kolla hur tändstift, rotor och fördelarlock ser ut nu efter du kört lite. De kanske pga av någon annan orsak är trasiga igen.

Annars är en rejäl service alltid bra och byta tex bränslefilter. Gå över alla vaccumledningar, kolla att motorn inte drar tjuvluft, inga avgasläckor etc.

Will do that tomorrow! Also bought new sparkplug cables! The vacuum hoses seem to be oke. Also checked the rubber sockel between the förgasare and the engine, that one doesn't suck in any tjuvluft

Al the sparkplugs look the same and good(in my opinion) arches are grey/white and the bottom plate is black. putted the new sparkplug cables on the car, but i have to wait if that has given me a good result.
the intire exhaust system is bin change last year, so i think that will be fine.

will change out the branslefilter tommorow,
thats in the backluka right? under the carpet. black metal plate with 3 bolts?

more ideas what i can look at what the problem can be?

Även om du nyss bytt avgassystemet kan det ju finnas en läcka, tex slarvig montering, tagit i ett fartgupp och dragits isär lite, någon spricka i en svets. Läckage kan lura lambdasonden och då ändrar den insprutningen...

Nästa steg när motorn är i gott 'mekaniskt' skick kolla felkoder.

bränslefiltret sitter under bilen på din modell tror jag, under baksätet på höger sida. Du kommer åt det genom att lyfta upp bilen.
När du lossar anslutningaarna till filtret linda en trasa runt då det ska spruta ut lite bensin.

I looked today at the exhaust system and it seems to be oke.
the only thing, there comes a bit of smoke btween the cilinderheads and the exaustmanufault(the iron thing the 4 exaust channals go in to one, the carbarator is bolted on top of that piece)
dont know it that can be the problem?

pulled off the plug from the lambdasonden and the motor still went up and down a bit in rpms

any other things it could be?

also checked the carbarator sockel(for pulling in false air) and it seemed to be fine to

it is a bit oily around the rubber sockel tough, on top of that exaust manufault

Now i found a hoze that goes down from the airfilter house to thaat same exaust manifault, that has holes in it, the hose looks like a fexible ventilation hoze. could that suck in false air?
