yes, that is one effect of egr blanking, egr displaces some of air during the pre-combustion. which makes the combustion reach lower temperature, but also lower the efficiency of the engine.

hows your running now? any change in mpg?

Whether its based on fact, or speculation, but keep an eye on the turbo.... in essence you are running the engine hotter now, the oil will get hotter, and so will the turbo. It has been rumoured to cause turbo failure by blanking the EGR, but like I say, whether this is always the case I don't know.

well been driving most of today and its running crap now,its spluttering all the time now,its does it most when im driving nice an steady at 30 40 50 60 70 etc,i thought the blanking plate was ment to make it smoother not worse....

putting the blanking platr in on the right hand side of engine (as stood at front of car) wasnt to bad to do..

how hard is it to remove the egr to clean it...i see its tucked away and impossible to see ...

In essence, removing the EGR, has probably made it worse as the car is designed to have it there, i.e. the ECU will be expecting it and the measured air flows, etc etc will be different without it. The EGR would have been open when driving at constant speeds, which ties in with your running issues at constant speeds.

Remove the blanking plate and take it for a drive.... see if it goes away again.

I personally wouldn't be happy that the water temp has increased by 10degC or so by doing this

Egr blanking does not work on modern Peugeots.
Its just better to have it working correctly.

Not sure where it is located on the 90, but when I had to remove mine to clean on the 136 its not that bad - only a couple of bolts holding it on the engine, and a couple more to hold each pipe on. Peugeot could have made it so much easier on mine and fitted it at the front, rather than the furthest point to the back of the engine they could
