I have experienced same  problem. Foot down, no power and when you finally do get to 50 it's shaking like a good 'un.

If no oil in your spark plug wells then your CC gasket is fine so I would guess one (or more of either your spark plugs, spark plug leads or your diss pac is fubared

I  was looking for the diss pac , i take it its hidden at the back under the scutttle 
Plugs look a pig to get out on the passenger side with all the wiring harness .

Strange how this fault does not show up on the paperclip test , guess its down to replacement of parts one by one until the faulty part is found

Yes! I'm doing that job tomorrow on my new purchase 

I'm not going to lie I found the passenger side a complete bastard to replace spark plugs. I had to remoe cable tray, ICV and brake servo cable.....even then number 6 took feking ages. With the scuttle off would be easier as a lot of the problem I found was getting the extensions on my socket to fit 

I think I'm right in saying that lead faults don't show as faults in the OBC 

[omega3000]

lead faults don't show as faults 

Not good.

I will have a go at taking it all to bits again tomorrow , other half wont be happy as the weekends ruined again with my head under the bonnet  Hope its a simple/quick fix

Before you go ahead and take it apart, bear in mind you will have to check which lead/spark plug is fubared. If it's the diss-pac then just a replacement needed but I don't know how to check which leads.

Spark plugs are dirt cheap so I'd replace all of these. If it's not them you can put it down to leads or disspac.

Hopefully someone else will be able to tell you how to check which one is to be replaced

Thanks webby 
Replacement leads from vx are so ive heard very expensive but ill do the plugs first/eliminate them then the leads ..failing that the diss pac last .

I did have the scuttle off a few weeks ago when i replaced the HBV and could have loosened/dislodged a lead while my hand was down the back ...thinking this ill take the scuttle off first so i can check the leads to the diss pack .

[Webby the Bear]

No probs mate. It's just the way I'd do it. Someone may come along and suggest a better way 

Leads are very expensive from Vx but I'm sure someone (Daz, I think) recommended a cheaper quality set. I'll try and find the thread 

As for the diss-pac (if it's that that needs replacing) I'm not aware of the cost... might be worth a PM to one of the breakers on here... Rob, Albs, Twig etc

That's certainly a possible so defo worth checking first. While you're at it just for peace of mind make sure the leads are pushed down directly over the spark plugs. When pushed on they give a satisfying ''click'' so you know they're on

Totally threw me when the car started doing this today , its not missed a beat since ive had it and ran perfect this morning . Then after a short park up the drive home was very eye opening , if i tried to accelerate the whole car shook so kept it to 50mph and limped the car back home ....no warning lights nothing and the eggy stink from the exhaust was a mystery as well . Im no expert i just try and fix the best i can so hoping i can solve this without too much hassle .

Will let you know how it goes ...thank you once again but if there is any help available i would appreciate it from anyone that lives near or anyone who has any other ideas how to tackle the problem ....all TIA 

[omega3000]

Is there any other omega tech heads on here that can shed any light as to what i should be looking at ? If there is a way i can check the system without pulling the car to bits or something else that has not been mentioned that would cause the car to be rough running ...just a quick help as im not very keen on pulling the car to bits in this weather if there is another way

It does sound like missfire on one pot. I have a similar situation. I had a blocked breather which led to blown cam gaskets, so oil in plug wells. I fixed it all last weekend, however I maybe didn't dry out the coil packs fully, and sometimes on LPG ( which puts a higher load on the sparking system) it missfires, Sometimes I can hear the slight tick of a spark going direct to the block. If I drive reasonably and avoid planting the right foot, its fine, however once I did accelerate fully, I got missfire, the ECU shut down one cylinder, and a 6 pot engine running on 5 shakes a lot, and put on the lambda light. I got over to the hard shoulder turned off and back on, car now running on all 6. I am waiting for a warm, dry day to clean the coil packs out properly.   

It is possible that your problems are caused by something else, (poss breathers blocked ? ), which can lead to a sparking problem. If you get the shaking again, see if a restart cures it. Taking the scuttle off is actually very easy; I was a bit apprehensive initially, but a few clips, wipers, one screw and its off, and it makes seeing things so much easier. It makes doing the breathers very easy, esp if you use my sons air pressure method !.

Best of luck,

Ken

Thanks ken , i have took the scuttle panel off and the wiper motor is out but still cant see how to access the diss pack . Took off every breather and cleaned them and the only one that was partially blocked was the one that goes into the metal housing drivers side back of engine ...the small breather pipe next to the larger one from the Y breather .

I can barely just touch the coil pack as there is a mass of wiring on top hiding it 
Took the drivers side plugs out and they seem fine , cleaned them and started the car back up and still the hesitant throttle response ...its not bad as the car ticks over good but a soon as its revved you can tell its not crisp just like a plug is not sparking .

Have no choice than to strip out all the harness passenger side and replace plugs then ill do the drivers side . While i have the passenger side harness out the way will i be able to check connections to the diss pack better that how ive been trying 


If i was to guess i would say its running on 5 cyl when under load ...

i thought if the diss pack was on its way out you tend to loose 2 cylinders. sure ive been told that.
