My car is using 1.4 loom but 1.6 ecu as it's got a better map. EGR valve sensor t the back of the inlet manifold cn be disconneted without probs. Mine has. The vacuum valve part of the egr near the pasenger side suspension turret can be disconnected (hose wise) but not electrically as it'll bring up a fault code.
It sounds like your car has gone into 'limp' mode. EGR cannot cause this. What other sensor is disconnected? Crank sensor and camshast sensor ok? Are you using ll the same sensors that came with the loom? Also is your knock sensor ok? I.e. torqued up correctly. This could cause 'limp' mode.
Also did you use the 1.4 injector loom. (i.e. the looms splits in half at the big blue connecter. Are you using the 1.4 part?) Could be anything. I know this sounds obvious but hve tried the paper clip test?

Loom is the same, ECU is different.

there are 3 differnt types of loom, main difference being the knock sensor wiring.

I believe some have 1 wire knock sensors others have 3 wires. Could be wrong. I know on some you hve to chnge some wires in the blue plug to make up for the difference. It would help if we knew the fault codes.

the loom and ecu is from a 1996 corsa, engine is from an x reg car, i'm not sure what the knock sensor is? will my car have a knock sensor or is it only on later cars?
I don't know the name of the other sensor disconected but it is next to the egr on the standard inlet and is not the one with the tiny plug, if that helps.
the small loom on the end of the big blue conector is the newer one from the 1.6

when i plug the 1.6 ecu into my 1.4 loom the engine turns but won't start, am i right in thinking the knock sensor cuts the fuel to the engine and stops it starting? and if my car does not have a knock sensor because it is an older car that may be why it won't run with the newer 1.6 ecu becuase it thinks its missing?
thanks for all the comments so far

If it's a tiny 1 wire connector next to the egr valve on the inlet that'll be the knock sensor. You need that connected other wise you car will be forever in limp mode. The knock sensor is usually black and round with a bolt through it. It's just bolted to the engine block under neath the plastic water pipe at the back of the engine. Your car should have a knock sensor. All 1.4 16v did i believe.
When you plug in the 1.6 ecu do you change the transponder and the chip in your key otherwise it'll never start because of the immobiliser. Providing the ecu is from a car manu'd after 1995.
