yes it's running good, it packed up in mersey tunnel yesterday, i replaced coil pack and its fine now, but i have noticed that when its ticking over at the lights, the tick over is not constant, the engine has a very slight shake, and when i put my foot on throttle it has a very slight hesitation before it revs
Timing could be out, needs a service. Also how much petrol are we talking? Could be a leak somewhere

there is defo no leak, am getting about 30 mile for £20
For that there is either a leak or a hell of a load of black smoke from your exhaust!
A leak isn't detectable as the petrol evapourates!

there is a lot of pressure release when i remove fuel filler cap, so i assumed there was no leak, as i thought if there was there would be no pressure release, there is no smell of petrol from car,
Shouldn't have pressure from the petrol cap :S I never have
Any black smoke?

no, no black smoke, its a strange one, am actually thinking of getting rid of it, i just can not keep up the petrol costs
Well there is an obvious fault somewhere and I can't figure out how the petrol is pressurising
how many miles has it done? without being rude, it may be pretty nacked by the sounds of things... i cant seem to figure out the problem is if your certain there's no leak, take it to a garage, get it checked for a leak, if the head gasket was gone completely you would feel a loss of power and most likely drinking coolant, not fuel.
Sadly thats as much as i know im afraid! Good luck!

After a quick search online the only 2 causes seem to be a faulty pressure regulator or a fault with the petrol return to the tank
Every car I've ever had always makes a air hissing sound when I take the filler cap out and fill it up with petrol when its empty. You don't ever get this?

On the car with the hissy fuel cap the breather must be faulty. Look under the rear wheel arch . If its clogged with mud that's likely the cause.
