On the sheet of icy snow outside the house I have noticed that there is a 'new noise' that I couldn't identify. Wondering now if it was the ABS pump activating the brakes?

Yep. You can hear the ABS pump start (and see the lights go dim at night. It's obviously thirsty).

well it certainly drops cylinders on the non-dbw cars

Yep... To the point where if it's still struggling for grip you stop moving if you don't switch it off

Same as mine then.
 Unless yours is fubar'd too as TB suggests with mine       

The system works pretty well when working, but cannot overcome poor driving - floor pedals on slippery surfaces is goign to be like floored brake pedal in this weather; the system will stop the wheelspin, and reapply all 200bhp, then light them up again.


So, either yours is bust, or you can't drive

I assumed the former

Mine is fine but my road is now so slippery I can only just get along it being very ginger with the throttle... Night before last it wasn't as bad as now and all I did was select drive and lift of the brakes (no throttle) and the rear and was fishtailing

Stil driveable, but with care and generally with TC off

I'm with you Lazydocker  If the road is ice, no amount of electrical aids is going to make tyres grip. My Omega was last used between Christams & New year when it snowed then. I took a run up  ... twice ..... but it wasn't having any of it.

I also agree

Snow mode on box, and TC can help though.  But you can't put a shine on a turd, if there is zero grip, there is zero grip!

Yep... That's the problem at the moment. Still... It's just about doable

It applies brake to spinning wheel. If that not cure wheelspin, it drops 2 cylinders I believe, if still not preventing, cuts more

I didn't realise that the Omega could apply the brakes :-/

The TC on my 1994 manual 2.5 V6 CD was useless. Hit a wet manhole cover with the throttle open and one wheel would spin up, the TC would cut the power, the wheel would stop spinning, the power would return and (without spinning a wheel) the TC would cut the power again. If you kept the throttle pressed it would kangaroo up the road

It would do the same if you opened the throttle on the crest of a road hump.

My 2003 auto 2.6 elite is far far better. On the same wet manhole cover I can floor it and not feel when the wheel is on the cover.

On the sheet of icy snow outside the house I have noticed that there is a 'new noise' that I couldn't identify. Wondering now if it was the ABS pump activating the brakes?

Only mini facelift and better apply brakes, as its a true 4 channel system. Pre 1998 is a 3 channel system, thus ABS ECU canot brake individual rear wheel

Another nice surprise

I have had this car since September and I am still discovering improvements that GM made that I wasn't aware of 

I now realise that the facelift is much more than just a tacky nose job and a cheap looking interior

Many of the technical improvements came in with mini facelift, including the ABS one.  Facelift introduced a few 'comfort' improvements - eg superior climate, better seat heating etc.

better rubber paint on grab handles etc

..... or is that rubber paint that is better at coming off?

Glad I found this post. I was getting worried.

After a short while of spinning wheels in the snow my engine sounded terrible...popping and spluttering all over the place...kinda mis-firing as if she'd lost power from a couple of cylinders ?
