Vauxhall Corsa car judders at high speed

Car: Vauxhall Corsa

Model Year: 2004
Categories: Running Rough, Starting & Power Loss
Hi.
For the past week when I drive my corsa at over 40mph, it judders for a couple of seconds.
I have changed the fuel filter and used injector cleaner. Also changed the air flow meter sensor
Problem still there. Any suggestions??

It could be the EGR valve wants cleaning. it gets clogged up with gunky deposits and this causes problems and sticks open.This causes problems with jerkiness so try using a toothbrush and some carb cleaner and a lint free cloth for best results.
