Need HELP

[clio_manu]

I got a problem with the minimum RPM of my engine, it's a 1.6 16V. The problem is that when start the car all goes ok but after 5 or 6 sec the engine starts to shake and it's a real shaking. I got skimmed the head of the engine so I was thinking if the knock sensor could produce this shaking?? or it can be that the engine is out of timing??, what other sensor could produce this problem??.

I need help I don't know what else I have to do, thanks.

Front O2 sensor

mine does this aswell and a mates 1.2 does it, so i just assumed it must be a common problem with the lower engined clios and it was nothing to worry about

Dude I mean is a serious movement at minimum RPM, I already check the plugs, it seems that the engine is good. A bad mount could generate this movement??, thanks.

Front O2 sensor

What sensor is that??, I know almost all the sensors of my engine but I don't their names in english hehe so If you can explain me where is this sensor would be great thanks for the help.

Front pre-cat lambda sensor. Hook it up to a diagnostic device and you'll know more.

I'm using 95 hehe.

But can it be that the engine it's out of timing??.

Depends buddy, did this occur immediately after the head work? You ron rating of fuel should affect the idle this bad unless your using some seriously crap fuel. If you can get an ObdII reader you should be able to pin point it a little better if its logged anything.
