Check the Tank vent, If it's starving or cutting out it may be creating a vacuum on the tank. Open the tank a bit and see if it still starves at higher RPM. If it runs fine, Located the vent tube and lean it out or clean the vent on the gas cap either way. If it's still starving for fuel, then look at the petcock. If it's one of the vacuum diaphragm auto types, the diaphragm is probably bad and will need to be replaced. Dump it and get a manual valve.

I think the word carburetor and ford falcon was mentioned which used a mechanical fuel supplied system. check for a cracked fuel supply line from the fuel tank to the steel body supply line.

Sometimes it seems that it dont get petrol but their are enought in tank it misses and when i rev it shes better for some distance then do it again

When you say it seems like it doesn't get petrol are you meaning that it starves under hard load / acceleration? If so, the fuel filter is the first place I'd look.

Honda accord 2005 2.2cdti,1st and 2nd gears are very slow on the rev uptake,but the rest of gears are ok,ive tried egr valve air flow meter and map sensor,still no good any suggestions

Try changing the fuel filter now. Higher revs on initial take of requires more fuel that isn't required at lower revs at speed in the higher gears. Could also be dirty air filter.

If the fuel filter is an item you suspect then I'm assuming the service history is a bit sketchy!! If so then I would definitely throw some new filters and plugs at the vehicle to start with. In my opinion though, if the fuel filter were your primary issue, it would restrict fuel flow and pressure and hamper acceleration throughout the rev range, especially at higher revs when the fuel demand is higher.

You could have a problem with a sensor, such as a throttle position sensor which isn't metering fuel correctly until your foot is flat! This should be evident in your fuel consumption.

My suggestion is a good service and then a diagnostic check for fault codes to guide you in the right direction. The service would be preventative maintenance but don't spend money on expensive components blindly- get it diagnosed correctly so you aren't shooting in the dark!

Here's hoping the service sorts the problem out! Good luck...

My mazda eunos will not rev over 2500rpm. And when I rev it over that the revs go up but straight back down again. Eg spluttering. But badly. I have changed the feul filter as it seemed it was being...

I suggest you check the fuel pressures and delivery volume before you replace any more unnecessary parts...

Don't spend money until you know what is wrong and that shouldn't be guessed but discovered by careful and systematic checking.

In addition check the plugs and spark power and quality

Cluster? or a simple sensor?

First, change the fuel filter, sounds like it is fuel starved.  You're right, the fuel pump will generally wither work or not, a clogged filter will only allow a certain amount of fuel through, limiting RPMs
