OK, went outside 10 mins ago after disconnecting battery, taking off the kick-guard, disconnecting selespeed ECU plugs and giving a clean with contact cleaner. Put back together and went for a test drive. She was all nice and smooth and when the revs dropped down to a point the gears downshifted as they should. She was all singing and dancing and I thought "great, finally fixed" then turned around and headed home. Then coming into the estate "Selespeed system failure" reared its ugly head again and car stalled. WTF I thought, give it a little chance. Started her up again and headed for a speed hump and let the revs drop. STALL again. ITS STILL NO BETTER, HELP!!
I'm thinking to check the relays next then or failing that cold the selespeed ECU be faulty?
EDIT: Iain - looking at your post #8 now..
Maybe the crank sensor (now thats more plausible because its not picking up engine speed? from the main ecu - but then why no fault codes on it?
