Cutting out / Stalling

[gjm]

just recently my '92 Griff has taken to cutting out every now and again. it usually only happens when i slow down from a reasonable speed as i approach a roundabout or t-junction. when i am in neutral the rev counter gradually drifts below 1000 rpm and the car stalls. it usually starts ok, or i bump start it by knocking it into 2nd gear if i see the revs fall away. i have checked for loose connections on all the plugs, disrtibutor cap, leads etc and the car is not overheating (so i don't think it is vaporising fuel). anybody got any ideas. i had a hunt through the search section and it it seems a few people might have suffered similar problems.

thanks for all your replies. i have cleaned the stepper motor - made no difference, although it was pretty filthy and i am reluctant to splah out on a new one just yet. disconnected the battery for 10 mins to allow the ecu to reset itself (not sure if that really works!)- no difference. am going to try and clean all the earth points over the w/end and if no joy then its off to the local tvr dealership.
