Known here in the UK as a Vauxhall Carlton  ;) ;) ;)
Where are you feeling the vibration? Steering wheel? All over the car? Have you tried getting your wheels balanced? You might have lost a balance weight from a wheel.  :y :y

Vibrating from where ?
Is it the steering or is the whole car vibrating ?
Any warning lights or codes
 

Must type faster lol  ;D

I came in to say exactly the same - if it's through the steering, I'd be looking at wheels, tyres and suspension.

I am guessing that this is an engine misfire problem from the ignition system but need more information from Omegaly.

Like a DIS pack breaking down on the V6 engines. Don't know how the spark is provided on an Omega A (Carlton 2.0 litre engine)

Check also the breather pipes - one at back of engine on right as you stand at front comes upwards from bottom of engine to a small hose at top. The other comes from the top of the rocker cover (on top of engine) to inlet manifold.

Correct - right at the back and an arse to get to!

All the same a new cap & rotor wont go amiss.

sorry for late
Vibrating all car 
and engine rpm raise up and down
 i give car more gas but problem still same
wheels is new and very good condition
And this problem start only
when i became near to 80 Km or above it
ignition  time is ok no delay
Today i change the spark and cables
and buy new air filter
because may be what i buy it before is not good one
and Performance of car before reach 80 Km
is excellent

Could be.
That is the Idle Control Valve (ICV).
An air leak there will mess up the cars settings at any speed.

but only at speed 78 to 100 car work like engine had damge but
i fix the leak after 2 hours from now but problem still with me
my friend tell me he will buy high quality spark cables he think
problem with spark cables 
is this real spark cables can make car work not good at only speed 80 km - 100 km

Possible but unlikely.
I would first get a new distributor cap and rotor arm.
Whe refitting the distributor cap be careful not to overtighten it as it can crack quite easily.

Also - are you sure the vibration is coming from the engine?
Check the propshaft centre bearing. If that has failed you will experience vibration.  Check also the vibration dampers at both ends of the prop shaft.

look with me car vibration and rpm raise up and going down
 { when speed reach 80 Km\h only }
Rpm meter it came like crazy showing things like engine is down and up fast
but when car is no gears on . i push engine to the max value of rpm and engine sound so amazing
And about distributor cap
do you thing may be is reason for all this >
i can search for one and replaced , my friend can do it

Yes it can be the cause because there is a huge difference between an engine revving in neutral and an engine under load.

Be careful to get the correct type of cap - there are 2 different types depending on which type of lead you use.

Ok then it'll be either the fuel pump relay or the pump itself.
