Hi,
 I'm new to the world of Omega ownership. I have been given a 2.2 cd by my father in law as he has bought himself a new one.
 This one has been having problems starting from cold and running badly for the first five minutes or so in a morning. After that it idles well but is rather underpowered. It has been on the diagnostics at Vauxhall and has come back with a few fault codes.
 I have been reading posts on here for the last week or so trying to get some ideas of what may be causing the problems but i think i could do with some ideas from all the clever people amongst you. The fault codes that came back were:-

0650 - Control Circuit
0301 - Cylinder 1 Misfire
0302 - Cylinder 2 Misfire
0130 - 0₂ Sensor 1 Incorrect Circuit
0170 - RID Module

Any ideas would be much appreciated as i am a bit of a  novice to engines and the like but would like to think i am quite practical and being a bit cash strapped would like to know if it was something i could sort using the guides on here before sending it off to the garage

Thanks

0650----ignore
0301 & 0302----check plugwells for oil
0130---check O2 sensor connector/wiring
0170---check MAF connector

Hey bud
my 2.2cd had a similar problem- was bad to start when cold and when it did start,it was rough idling for a few minutes.took to my local vx garage who are great and after a few scratches of the head and about two weeks later they found it was the MAF Unit which they changed and also cleaned the Throttle Body.
Worked a treat on my Miggy!!

Went through a few things with similar problem myself.  Changed the plugs - temp fix,. Changed the coil pack - temp fix.  The only thing that really sorted it was new HT leads - not cheap.... purrs like a pussy now though!

No HT leads on a 2.2, it has dis-packs. Just one to try when starting from cold, unplug the MAF and see how it starts then

hi people, thanks for those ideas!
well i took it to a local garage and plugged it in there, the same fault codes came up as what did at vx, the bloke said that all of the fault codes could be syptoms of the missfire so advised to change the spark plugs. replaced them with bosch ones and plugged it back in, this time all other fault codes had gone apart from the camsensor fault code?
ive had the following changed on it: dis pack, throttle body, camsensor, spark plugs. so seen as though ive already had the camsensor changed im not happy to pay for this to be done again!
i was thinking mabey hving a look at the engine myself but im not sure where to find the sensors and what i shud be looking for on them?? could anyone help me with this please?
also i did unplug the maf and the car seemed to sound sweet....but i hvnt done this from a cold start yet! the car is still poping and spluttering when started in the mornings and i hv to leave it to 'warm up' before setting off, if i was to set off before giving it time i wud have my foot to the floor and the car wud go but only at 10mph it has NO life/energy!! it also loses power for split seconds when being driven? please someone help me,, ive got a feeling its something simple lol!
