sorry folks,
problem was I think when remove fuel pipes some fuel leaks out and after reconnecting take more time (starting 5 time for 10sec.) to start engine. I guess it need to pump fuel again
now I can drive with replaced ignition coil, witch is little better then my old, and wait for new one.

CPP - Coil Per Plug

Each unit contains 3 coils, one of each attaches directly to the top of the plug, a low tension feed from the ECU goes to each "coil pack" as they are sometimes called, the ECU triggers the low tension side, and the CPP makes the required spark at the required time.

"Coil packs" are different each side .. 1-3-5  and 2-4-6 respectively .. it's called progress ... effectively 6 ignition coils instead of one as in the old days of distributors, and if just one fails you have to replace 3 ...

Thanks dbug and Entwood for your feedback.  I understand now.

I am still getting used to our cars not having carburettors and distributors.  But no leads; that is something else!!

I was thinking (well I do occasionally!) about this and all electric cars.  Do you all think that when something goes wrong we will still be able to replace individual parts, or will it be a case of a new complete motor assembly every time.  After all most electrical components, small and large, are now "not serviceable", being sealed units. I can just see the day when the whole electric motor unit is replaced when not running right!

....

Really!
 ......

That was my reaction at a show at Tatton Park, when a 3.2 owner told me his car didn't have HT leads. 

So Andy, how do those systems work then without leads?  I cannot get my head around that one!

Just looked at the picture more closely.................so do those plastic "strips" over where the plugs are contain leads?

As Nige says, coil clips directly to the plug ..... No HT at all.

Not all manufacturers do it this way, some, do actually have an individual, replaceable coil on each plug.

Well it looks very neat Andy, and it must reduce the risks of arcing cables due to them being damaged so easily.

Do you know if this system is now common in modern cars?

A lot seem to be going that way. Others would be better placed to answer though, as they work on a greater variety of cars than me. SWMBO's Smart still has HT leads though...... 3 coils, each with 2 leads (3 cylinder engine with 2 plugs per pot  )

today I receive and mount new ignition coil and get new error P0300 0301 0303 0305 
then I put new fuel 100 octane and tube of Liquimolly injector cleaner. Now I dont receive new error but get stil unstable engine in idle (500 600 rpm)
is it possible that injector cause error 0300...

0300 is a 'general misfire' Do you still have the EML light on? The fault codes will be stored for a little while irrespective of you fixing the fault.

Injectors are bullet proof, lets go back to the start of this issue. You fitted a possible faulty coil pack? What made you change this in the first place?

 

[manolo]

shit,
after 150 miles open road no problem when driving
first stop and running in idle get eml light
errors
0300
0301
0303
0305

what to check next when ignition coil 1-3-5 is new???

According to yourself, its not new & suspect.

First I have misfire on 1-3-5 and unstable engine in idle.
then I receive ignition coil for 1-3-5 bank from guy from forum (not new, he says that he have some problems but he can drive with)

As before, what made you change it in the first place?

[feeutfo]

Check the plug and wiring to coil PAC on 1,3,5.


How old are the spark plugs?

[manolo]

Igntion coil is new and spark 2 year & about 30000 km

But you said you bought it from someone from the forum!?

Replace plugs. Might be worth a re torque, they come loose.
