[EXT]

Listen to the engine, especially when climbing hills or going slowly in a high gear, you may here a knocking / tinkling sound from the engine - this is pinking / knocking (also known as pre-ignition) and is far more likely to happen with only one plug per cylinder being used. Bear in mind the jazz engine has a remarkably high compression ratio (10.8:1) and the only reason it can run successfully on 95 RON fuel is because it uses 2 spark plugs per cylinder to detonate the charge from both sides at once and shorten the flame path.

Knocking can cause damage to the engine and you should get the problem sorted ASAP, don't wait for next service.

In meantime use a higher octane petrol ( 97 RON BP Ultimate or Shell 'V' power) to help the engine cope.

Sounds very much to me like problems with the EGR valve, see this forum under"infamous EGR valve"

ok here is my findings
i disconnect front ones with back ones connected than drove,jazzy jerked as normal.than i let it idle and disconnect one by one
and connect it back.each time when i disconnect car misfire.but when all 4 are connected it idle fine.
only when i drove it jerk. fouled plugs.................?? what u guys think?
car is out of warranty. honda dealer are 3 hours drive from my place.
took out back 4 coils. 2 of them were little white spark sign at the end of coil where the rubber
that holds the tappet.i thought it these 2 coils are bad.i quickly put the salo tape arround it to check it stutter.yes it was stutter the same.its mean is defenately the plugs.
any other way to check further until i take it to the dealer?

year 06 and 104000k, i realy dont know what is the cause, other forums i visited where ppls had
same problem.

It wasn't too many years ago when VW / AUDI group had major problems with ignition coil packs on their cars due to bad quality and had to replace literally millions of them - Japanese cars never seem to have a problem.  

I had to replace a couple of ignition coils on my wifes Punto as well (no surprise there knowing reputation of Italian electrics).

At least DSi Jazz with 8 coils won't stop completely if a couple go bad

changed 2 faulty coils and did service done by honda dealer all fine now.
