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. Gary |

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 Edited by eagle3, Tue Feb 3, 2015 9:57 pm.

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. |

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. Gary Edited by Gaz2N, Wed Feb 4, 2015 10:03 am.

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. |

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

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
