CAR SHAKES

Hello to everyone, I am from south america (Ecuador) I have a Renault Logan 2006 1.6 engine. I took the car last week to the dealer for the usual maintenance but after that for some reason the car shakes, what it means by shake is that if I start the car on Neutral the car starts shaking in the beginning i thought it was the injectors or any sensor but i took it somewhere else they check it all even the put on the computer and they notice is something about the combustion, that is below the average that is all they told me and they said i should take it back to the dealer.
Does anybody has face the same problem.
This is the first time it happens.

I would get the engine mounting brackets checked they could be loose I dont see how though after a service and it should not be down on a cylinder BUT go back to your dealer and demand a combustion check !
Is it a petro or a diesel ? It is not uncommon for a Diesel to shake ONCE at the startup and ONCE on turning off
Keep us informed and also a BIG WELCOME TO YOU

Thanks for the comment, something else when i have the A/C on it even shakes more.
Tomorrow is monday and i will take it to the dealer. The car is PETRO (gasoline) model.
That is something weard, this never happened before.

I will let you all know what happens.

Homero

shake as in hulahoop??

Push down ALL of the spark plug leads and also check they are all pushed into the distributor Could be a loose lead ...In fact it maybe is this !!!
Have you had new plugs just fitted?? If so maybe the plugs are not tight or EVEN to LONG if to LONG its BYE BYE Motor
Get this checked out

Hey thanks for that tip....I thought of that. they are new, but i was told yesterday in another place that this sparkplugs are one diode instead of two diodes sparkplugs.

The dealer is using one diode sparkplugs instead of two diodes....could this thing be an issue too ? even though they are new. ?

yes this could cause the engine do hulahoops. go through the manual on the actual spark plug requirement and try replacing ones you have.
also check the cables around spark plugs.

You only need one diode plugs in a logan anything else is just money grabbing But you DO need the correct size which you will as Mir said find in your handbook

Feedback ???

Hello to everyone.
well finally the dealer fixed the issue. they checked and told me that the shaking was related to a piece which needed to be replace i will take a picture of it and post it tomorrow. the shaking went off and hopefully it was this.

regards.

Hey your answers are getting a bit wierd
Knocking or detonation noises are normaly called pinking this is a phrase used in older type motors without engine managment like Lamdasond
and also pinking will not cause any discomfort in driving it (USED TO BE A RATTLING NOISE) due to unburnt fuel Sheru are you pulling our legs a bit here with your Questions and answers

True, pinking should not cause vibrations as those mentioned above. Sounds like some part which may partly be bolted to the frame and engine with probably rubber bushes in between?
