That should light up the eml. The ecu usually pulses the valve and looks for a change in rpm.
On a petrol engine the egr valve when working increases engine efficiency at part load, and keeps exhaust gas temperatures down, so the valves last longer.
It is disabled at full load.
Diesels are a different story...
If it suddenly breaks, go back to the last thing that you did before it broke and start looking there

Yes i do have a problem engine starts fine runs good until it warms up then starts to idle rough as hell
Cant really get to the bottom of the problem its a 1.6 motor with jim jam inlet ecu and fitted wih the green/blue baleno injectors.
If i introduce a very small amount of air into the manifold by just cracking 1 of the vac hoses it smooths out and runs good and as the EGR pipe runs into the manifold as wondering when does it feed the gases back in and could it be the valve is not opening or there is maybe a blockage,
EGR just seems to be one of them thing you have to live with but is hard to grasp what effect it has

could be a coolent temp sensor when it warm the ecu may think its still cold and is putting to much fuel in and when you crack the pipe off you put more air in which is going to weeken the mixchure down may be
