well people didn't think it would be so smooth lol

the engine is idoling funny keeps going up and down

and think its running abit high cant adjust the throttle as the linkages or maxed out and sitting on the switch

if i start it and dont touch the accelerator it dont rev up and down

only starts to do it if i rev it

what you think it can be

just fitted a 2L in a 1.8 190e

the old 1.8 engine didn't do it

did have to change the temp sensor over as the 2L one didnt fit the 1.8 loom

one day it will run problem free lol

heres a video of it iv all ready reved it so its doing it :)

Posted Image

got this picture of the net iv got a spare connector on my 1.8 loom I think it plugged in to the icv but cant find it on the 2L engine is it meant to have one as the old 1.8 engine did...

Sounds like you may have two different versions of KE maybe?

Do you know if the 2.0 was out of a car which was much older/newer?

I would suggest that you look on the Mercedes Benz Club technical archives as there is a lot of info there about tests to be carried out on KE. You'll need to be very methodical.

Good luck.

I was a little concerned about that. The 1.8 is probably catted i would think.

I don't know why you keep starting new threads.. http://mercedes-190.co.uk/search/?c=4&mid=3040644

whats a KE

can i just fit the icv to the 2L engine take it of the 1.8

or was thinking about taking the whole fuel system of the 1.8 and fitting it to the 2L would that work

don't know the age of the engine all i know is its from a 190E

that picture is from the net just to let you know



new problems new theads sorry about

No it's all the same topic.

Although you need to get confirmation from someone more familiar with the M102 that might be the way to go.

It's on the left side of the block near engine mount.

KE is the injection system.

I believe if you change over the intake manifold (putting the one from the 1.8 on the 2.0) you'll have an engine that performs as a 1.8 as apparently they are internally different. It's not as if there is much of a gain from a 1.8 to a 2.0 so if this gets it running properly it's probably the best option.

As I said in my pervious post the best solution is to consult the tech archives in the Mercedes Benz club website, or you are guessing.

Are you sure you have connected the EHA valve as you should not have a spare connector in that area.

The intake side and fuelling bits should be the same, it's the block that differs, bore and stroke variations and all that.

Is it difficult to start? Hunting idle often happens when there is an air leak and ecu tries to compensate for unmeasured air coming in. Check breather pipes and vacuum lines, even a hairline crack will throw the ratio out. Worth checking anyway as one of the things.

Check my thread out. I had two rogue hoses - could be the same ones.

If the 2L was auto originally it may be a hose for kickdown or something. just cap and forget it if it doesn't do anything. The hose colour code is probably identified in some merc manual somewhere.

if i suck the vacuum pipe iv took of the engine it starts to ruvs up and stays high then starts to rev up and down

but think its starting to rev up and down agen so back to to same problem

when i took that vacuum pipe of it stopped

but now it does it every now and then thats why i through it stopped

if i put that vacuum pipe back on it does it all the time like in the video

thanks greek taxi all my vacuum are the same as yours in your pics

the vacuum what i cant find its place for is coming from the big rubber boot under the injection system

where you plug that pipe in under the big rubber boot and then it goes up to the icv I think its a icv its at the back of the engine next to the water pipe for the matrix thats where the spare vacuum pipe is coming from well the vacuum pipe goes on a thin pipe then joins up to the icv

my 1.8 old engine had whats in the picture icv but dont have a vacuum line

on the new 2.0L engine i didnt have a icv in picture well i don't think i do or did

i think i found it at the back of the engine

so what i mean the icv connects to a pipe then connects to the rubber boot under the injection system well that pipe what connects to the boot has a vacuum line coming out of it and dont know where it goes from there...

Jason, your post at 9.47am, picture 2, I don't have that valve on my engine (1.8 manual). And I can't see anything similar elsewhere under the inlet pipes.

the 1.8 had it in the same place as the picture

but the 2.0 engine i through it didn't have one because its not in the same place as the 1.8 one but think i found it at the back of the engine where the water outlet is

think its the same part because 1.8 the pipes what come from it look similar to the 2.0 pipes only thing different is the icv is at the back of the engine

but on the 1.8 icv pipes it was just pipes but on the 2.0 engine the pipes have a vacuum coming from a pipe what goes to the rubber boot under the injection system.....

are get a better picture some how
