Am I to purchase a new Coil Pack ?
As I have the above code will a new 2-4-6- Coil Pack cure my problem?
Should I get both sides or just the one, as there is a history with this car on cylinder 4.
This was taken from SARANBAILEYS original Advert for the car.....
.....I have had the car Tech 2 on missfire as there was condensation (the cold weather caused this) in plug number 4 causing it the problem, now cured. Engine management light off Cats both working fine.
So, are we agreed that it is pointing to the 2-4-6 bank of Coil Pack?
I really need this sorted as my CRB will be back this week and I need the car for work.
If this cannot be resolved I am going to have to bite the bulllet and get shot of it, for obvious reasons I need reliable transport for work.
All help greatly appreciated

if you have a miss fire yes, if not no.

Are you aware of any engine issues while driving?

May well be an old code from previous. As you can see from the video in the paper clip test thread, my car had 0300 and 2 other missfire codes when i got it. It has been fine in my possesion.

Try not to panic Panic Pants.

Code 0300 means ' random/multiple misfire'. You can see what the codes mean if you go to 'maintenance guides', then 'index', then 'engine management codes', then 'Y26SE and Y32SE codes'.

This code points to a random misfire rather than a specific cylinder, and when you bought the car, they stated that the fault on cylinder 4 had been seen to and cured. I'm sure James would have seen a problem when he changed your spark plugs if there had been one.

I wouldn't go buying bits and pieces on the off-chance that it may cure the problem. As I said before, this is not a big deal at the moment and the car isn't going to let you down. You drove it to France and back in a far worse state than it's in at the moment. You may need a new coil pack, but there's no point wasting your money yet. Hang tight to see if someone is able to give you a proper diagnosis.

[Kevin Wood]

Yep. Proper diagnosis being the key.

0300 means random misfire. In other words, the ECU is unable to determine which cylinder is missing. A faulty coil pack will always misfire on the same cylinder(s) so I think we can discount that straight away. £80 saved.

IIRC, the car had issues with a totally clogged air filter amongst other things which could well have caused a misfire. Were the codes reset at that time?

Do you know for sure that this code appeared since everything has been sorted out?

Does the car misfire or show any symptoms when driving?

Is the EML actually on or is the code just stored?

If the answer to the above is "no" you have nothing to worry about. Next time you're passing one of us with a Tech 2 get the codes read and cleared so you know that you are not dealing with historical information.

All the codes should clear after ? clean starts. Forget how many

afaik thats true on the old steam powered omegas Esty, these new fangled drive by wire omegas are a bit more advanced in the ecu (thats Electronic Control Unit for you olduns) dept. come on gramps, keep up.

The very same code on SWMBO's DBW AStra G cleared all by itself, so I would imagine the same of a DBW Omega.  :-/

The codes cleared a few hours after James did the service. Then next day the Orange EML came on.

Do you know for sure that this code appeared since everything has been sorted out? YES, Definitley

Does the car misfire or show any symptoms when driving?
No None at all. Just stinks of fuel when starting.

Is the EML actually on or is the code just stored?
Yes, ON at ALL times.
Hope this helps.

You need to recheck the codes now. It could be IIRC 0420 and 0430 which is a common 3.2 problem and sorted by moving the lambda sensors.

Is this just from cold .. or every start

As a thought .. start it up, run until warm - I expect EML to be on if it had a problem starting ....  switch off and leave for 5 minutes.

Restart ... what happens ??  ie .. does it start well ?? is the EML light on

Trying to see if it is a cold start problem . or an "every start" problem .. if its the latter it might be the start of a crank sensor failure ?   you don't always get an indication of these until they give up completely

IME the 0420/0430 don't give any smell whatsoever ..

Smells of fuel ONLY from a cold start.

Starts on the button EVERY time.

Mine was fine first thing Friday morning, by 2 o'clock the car was on the back of a recovery flatbed with the caravan at the back     

[alunonhisown]

Just re-done the Pedal Trick and it stores only one code and that is 0300.

Yes, thank you Andy. Don't you just love it when these nippers are wrong.
