corsa 1.4 sport juddering issues

[BigDaveDJ90]

Hello people, im new to the site but cam accross it whilst i was looking for advice about my extremely frustrating car.

When the revs are between 1500rpm and 3000 rpm the car judders and its like its missing. Its only when the car warms up though, when i first drive it in the morning its fine. so i took it to the garage and they plugged it into diagnostics. it came back with EGR valve and lambda sensor and he also said i needed a new downpipe for the exhaust. soo nearly £200 later and all those things were fixed but the problem still persists. I really dont know what to do as its really pissin me off now. its had a set of new plugs recently aswell. the engine is the X14XE so any help or advice would be greatly appreciated as i cant afford to keep taking it to the garage.

Cheers guys.

Just been advised to get some ht leads as this could solve it?! Does anybody agree? I really don't know what to do other than throw a match down the petrol cap

Right I've spent too much money on it now and I'm sick of it. I've checked all vacuum pipes for splits but there are none. It's had: egr valve, lambda sensor, fuel filter, spark plugs, ht leads, coil pack, coolant temp sensor. I've checked all earths and all fuses and there's nothing that seems wrong. Can somebody please give me advice of what to do with it now. It's not sellable like this and it's too good to scrap. I really am stuck.
