Hi guys,
RobG kindly walked me through the process of adjusting my throttle cable but i still dont understand what's happened lol
Previously, i jam my foot to the floor from cruising and you feel the car gird its loins, drop a gear and you then fly to the redline.
yesterday, i kicked down and i felt it drop a cog but then made a climb to the redline without the girding its loins bit. ???
adjusted my cable as per robs help and it still doing it. i feel it drop a cog and it redlines but why all of a sudden has that bit gone where it feels like its summing up the energy to fly you away?
am i even making sense? lol
i tried it from all different speeds... from 10mph it didnt even drop a cog but thats im assuming because i was in 1st gear and there were no more cogs to drop lol
-
Ps, is it always just one gear it drops or does it drop two in certain circs? :)
-
Are the Multi rams working?
-
Yes mate i manually tested them a few weeks ago. i suppose due to the recent-ness of the weirdness i could re-check them.
As said its definitely dropping a gear then flying.... and that seems actually better than it taking a split second to gird its loins. i thought id post it just cos its a bit bizarre.
however, just took it out on lunch for a new 0-60 test... she did it in 9.3 secs!!!! not bad for a 14 year old and the book time being 9.5. i know its not an exact science but its good enough and confirms shes still nippy :)

Edited for accuracy :P
-
Hahaha 3 secs???? The stats say the manual is only 0.5s in front on the 2.5v6
-
True, but the 2.5 isn't full fat...
As our American cousins are ever keen to point out, there ain't no replacement for displacement...
And the 2.5 is nearly a whole Daewoo Matiz light ;D
-
So manual AND bigger engine required ::) ;D
TBH I find the baby V6 more than adequate for my purposes.... not sure i could cope with the sluggishness of a 4-pot tho :-X
-
Although after today i'm happy everything seems to be working normally.... if i felt compelled to test the kick down switch off the car is there a way to do it?

My 1.8 mummy bus will do it in just over 11 seconds ;D
-
;D Does it do it in that time without falling apart tho ::) ;D

Found this...

I'm not going through the hassle of pulling out the throttle cable lol
Does anyone know of a way to test it in situ?
-
Open road,sit at 60mph then floor it,should kick down to 2nd gear and watch the fuel gauge drop lol...
-
I find that mine drops a couple of gears when in sports mode, not so much on normal...
I will admit, going from a 2.0 to a V6 2.5 the Omega is like a flying machine compared to my mildly tuned Vectra...
-
minifreek..... say your in sports mode all the time.... does it ALWAYS drop two when you kick down? or is it just sometimes? :)
-
;D Does it do it in that time without falling apart tho ::) ;D
Unfortunately, no :( No car is as indestructible as an omega, they are bullet proof.
;D ;D ;D ;D ;D ;D ;D

Oh aye, some of the mad mechanics on here reckon the interiors will take a good pounding, when you swing a cat in them. ::) :P :-[ ;D ;D ;D

Depends on the speed...
Lets say for example, Im on the motorway.... I switch into S - get to around 70 and it changes up.... I go to overtake - kickdown and it sometimes changes 1 gear, if i really boot it - it changes 2 but then quickly cycles back up the box...
It only ever changes down 2 gears, but only if I proper give it some whelley to get into a gap...
Normal mode it will drop 1 gear but then quickly go back up a gear again unless I hold it on gear and keep the engine 'on cam' as they say....
-
Thanks mini....
not too sure how to work out if its dropped one or two if im honest :-\
theres only one physical down change but has it dropped 2?
-
You'll know if its changed 2 gears or not by the way the engine screams...
Mine... if it drops 2 gears - its like the engine is trying to crawl out from the bonnet but I get a sudden whoosh just after it 'gurds its loins' and it just oppss off....

I would be careful with your descriptions as you know what one of two are like on here, mentioning no names. ::) :o :P ;D ;D ;D

Yeah we should be careful what we say, I suppose we dont all have the mind of a child or a double entendre way of thinking...
-
My 1.8 mummy bus will do it in just over 11 seconds ;D
My DTi will do that in...
...no, that's a lie, it won't do it ;D
-
If you're passing webby, I will happily test. Warm the brakes up for me first :P

2.5V6 auto saloons were advertised as 0-60 in 10.5 seconds in the 1994 specification brochure,2.5 manual in 8.5 seconds, 3.0 auto in 9.3, 3.0 manual in 8.3. You will know if the kickdown is working properly or not - once they are going the auto picks up far better than the manual, and just keeps going. If the kickdown is not working then I cannot help you as mine is yet to fail.
-
The published figures are quite conservative on these Vauxhalls (and a lot of others from around that time).
There are some speed ranges where an auto is faster, but overall, a manual will beat it. Even if the Omega manual box is from a Victorian signalbox
-
Omega manual gear change reminds me of a 2000E Ford box. Except for BL in line motors, I have only driven tranverse engines since. First gear in the 2.5 is too low & second does not go far enough. However, still flexible fom 20mph in fourth.

I had a Honda Rover 216 with a fantastic 3rd gear. 20 to just shy of 120, rarely bothered with 4th or 5th ;D
-
Honda/rover 623 we had was amazing. Put it in third at 20mph and nothing could stay with it.
-
In fact, I think that was my favourite car.
-
Third is the only gear you need for fast B road blasting 8)
-
Thanks TB for the offer of testing. I may just do that (i'll pm you when I'm in the area). Cheers mate :y
-
Ps, if we find out the kick down isn't working what are the potential offenders besides the KD Switch.....

Nothing, assuming no car mats.

Kickdown on mine doesn't always downshift, it drops a gear when at 30mph but not 40-50mph. But mine is 3.2 auto with DBW and different diff to yours
