Xsara HDi engine stability problem at idle RPMs

Hello

I am desperate, my 2003 Automatic Xsara HDi drives perfect on high RPM but when it goes down to idle lets say on a red light or a stop sign (gear on DRIVE + brake + air conditioner) the engine starts to choke up some times it shuts down.
My mechanic cut off one of the vacuum controllers (out of the three in the back of the engine compartment)

I would really appreciate any help

Sounds like an EGR - related problem (Exhaust Gas Recirculation). The EGR valve seems to often cause problems on that engine.

It sounds like it's mucking up your fuel/air ratio at idle. The best bet would be to disconnect it completely.

I think I disconnected it, I disconnected the middle vacuum solenoid, (the one that has a pipe going into the unit on the air intake hose which I think is the EGR). After the disconnecting the problem reduces but it does not cease. The RPM still drops at idle sometimes but not always. What can it be???
Thanks

The unit you have disconnected is the EGR throttle butterfly not the actual EGR valve,follow the piping to the EGR valve,its bolted onto the inlet manifold near the timing belt side,remove & block off the pipe to it & try that.
