LRD1 1994 Engine Stolls Mainly at lower revs

[shaunwhite]

Hello fellas, this is my first post and I have a problem that I hope to solve with your help. I've been to a lot of service shops but without much success. The Disco 1 is Oct. 1994 gasoline, 2.0 MPI. The engine stalls after warming up at higher revs and at lower revs changes the revs chaotically. All sensors have been tested and found OK and comp does not show an accumulated error. Nevertheless the work of the engine is unstable. Any help apreciated!
