Omega General Help / Re: Maybe too buy 2.2 gls

« on: 25 February 2009, 21:02:10 »

I have 2.2 and i get on average anywhere between 23 and 26 mpg whilst driving around the town, and up to 36mpg on the motorway if you keep to the limit. Act like a grandad you may get a little more!

Omega General Help / Re: Fuel comsumption 2.2 petrol auto

« on: 19 January 2009, 18:18:40 »

Hi,

I have a 2.2 Petrol Auto Est, I am getting on average 22-25 mpg, But i have noticed that if it's really short distances and the engine is cold, then this is much lower. I travel 7-8 miles to work and back, and if i don't thrash it i can expect about 22-24Mpg. Motorway can be around 32-36Mpg, at around the legal limit.

Hope this helps

Omega General Help / Re: Head gasket failure? / coolant leak problem

« on: 19 January 2009, 23:35:21 »

HI,

Exactly what happened to me, not three months ago. All of a sudden the coolant level would drop, bad misfire on ocassions. The Head gasket went (No oil in water or visa versa), the water was going straight in the number three piston, and out the exhaust.

Basically it was fine until the engine was hot as the combustion pressure was keeping the water in check, the pressure built up - whilst driving, but when you then leave it ticking over, the pressurised water would then enter number three piston & out the exhaust. ( also when i removed the expansion tank cap, i could smell unburn't fuel.

I ran mine for 3 - 4 weeks, but is going to need changing and can completely fail at anytime!!

Omega General Help / Re: Tyres - Which brand??

« on: 19 January 2009, 23:04:04 »

There is no straight answer to a question like this unfortunately, Some tyres perform better in the wet than other's, but these tend to be of a softer compound, as such will not last the mileage.

Visa versa harder compounds are good in summer and on dry roads with the ability to give decent mileage but can leave you in trouble on a wet road, or damp raod.

Personally, and i think this does come down to personal choice and how much you are planning to spend. You tend to get what you pay for when it comes to tyres (with the exception of one or two), but I find conti's and dunlops tend to be better value without comprimising on quality and giving alround performance.

Omega General Help / Re: 51plate 2.2 Petrol Engine Limited to 4500 RPM

« on: 19 January 2009, 18:34:48 »

Thanks for the responses,

Sounds as if this is a everyday 'normal' occurance of the 2.2 petrol Autobox.

Well at least i know that there is nothing really wrong with it  

I will search for the filter, gaskets and Oil, then change this as soon as i have a free weekend with reasonable weather.

Anyone know what oil it takes and how many litres?

Right an update for you,

I have changed the Cam Sensor (purchased an original )and also cleaned all of the throttlebody and breather pipes (as i knew the small breather that goes to the throttle body was blocked). I have also used a bottle of Cataclean, to ensure everything is in tip top condition.

The fault is now resolved, the engine is responsive again and will happy rev over the 4500rpm to which is was limited to before.


You were right is was the cam sensor at fault.

next problem

When ever i am cruising along at about 60 -70 mph - betwenn 2500 -3000rpm, and i reach a slight incline, the autobox seems to change down to 3rd in order to maintain my speed is this a common thing with the autobox??  Basically it seems to change down under circumstances that i would not expect it too, or where the engine should have enough power to maintain my speed without changing down.  again any suggestions for this??

I'm thinking of changing the Gbox Oil & filter, as the car has done 100k now. any suggestions??


Thanks in advance Barry

Thanks for the responses to date, I will contact my local Halfords , hopefully they can read the codes without too much trouble and take it from there.

Thanks ...

Any idea on the price & best place to buy a cam sensor?? Also where is this located? thanks

Is it best to get the codes read first (just that i know this will cost min £50) or do i change the sensor and hope this will cure?? any thoughts?

Omega General Help / 51plate 2.2 Petrol Engine Limited to 4500 RPM

« on: 05 January 2009, 13:16:44 »

Hi All,

This is my first post having just joined so here goes and i hope someone can help me out. I have checked the current list and can see one of a similar nature but this was for the diiferent engine - apologies if this has already been covered

I currently have two problems with my car (51plate 2.2 Petrol CDX Est AUTO- latest facelift).

Firstly, I have had several instances of the orange/amber engine management light appearing, after running the car gently for 4-5 days the light will eventually go out. But if i accelereate hard or at full throttle, the light will no doubt re-appear, as this is when it tends to come on - following a drive where i have had to push the throttle fully open.

I have also noticed that the car appears to now be limited to exactly 4500rpm (wether the management light is lit or not). As i have an autobox this means i have to drive very cautiously, or else it will just reach 4500rpm and will not change until i lift off, wait for the gear change and then reapply the gas. I suspect a sensor failure which is now acting as a restrictor. any suggestions?

p.s. I am planning to clean out the throttle body and intake as i don't know if this will help or not, but i will await for response before carrying out any actions.

....................


Secondly an unrelated auto box issue..

When ever i am cruising along at about 60 -70 mph, and i reach a slight incline, the autobox seems to change down in order to maintain my speed (does this wether on cruise control or not, but more apparant when on cruise control). Is this a common thing with the autobox??  Not sure myself as this is the first auto box car i have purchased. basically it seems to change down under circumstances that i would not expect it too, or where the engine should have enough power to maintain my speed without changing down.  again any suggestions for this?? :-/

Hope you can help out  thanks....  p.s. I don't know too much about this car or what any of the parts look like or where they can be found, so any detailed responses will be greatly appreciated..

Thanks in advance Barry
