Vauxhall Astra, 1.4lsi, no power when pulling out, and pressure in fuel tank?

Just the last couple of days, I've pulled out in 1st gear from junctions and it just won't get going.juddery, and really slow up hills. When I took the cap off to put petrol in, it made a a noise like it was under pressure, or a vacuum. Someone said it's probably some kind of filter that's not letting the air through, and therefore the fuel. How do I find this, and check it myself? where is it and what does it look like?. I need to do it soon before something else goes wrong as a result, but I can't really even afford to spend 20 quid on it at the garage. Thankyou

Can't hack into that!
check your catalist.if its collapsed inside it will.. make the car sluggish.. it happened to me.,,,,,,,
It could be a whole list of things.

Try checking the fuel filter to make sure that is not blocked - if it is it will be restricting the flow of fuel and therefore reduce power.

You can also check the air filter - if that is blocked you will be running on a rich mixture as if the choke is on, it will start ok and then get worse as the engine warms up.

There is a breather pipe on the fuel tank that could possibly be blocked which could account for the fuel tank making the noise.

After this it probably starts to get expensive - is there white gunge on the oil filler cap which will indicate water in the oil and a split head gasket - are you losing oil or water?

If you want to learn to do it yourself I would suggest buying a Haines manual for your car.

Good luck
Not sure about the sluggishness, could be anything, electrics, carb or plugs but there is supposed to be pressure in the tank. good luck
a little knowledge is dangerous, why do people insist on putting stupid answers on this site?
fuel tank breather is blocked, it's part of the cap, change it!
as the fuel is used air cannot get back into the tank, this creates a partial vacuum, (remove cap, sound of air rushing in), the fuel pump then has difficulty 'sucking' the fuel out of the tank, not enough fuel from tank=poor performance!
hope this helps
