Had a new clutch fitted yesterday, no problems before going in (apart from clutch!). On collection the car would cut out when stopping at junctions etc. Went straight back to the garage and he said that the ECU was re-learning its settings and that nothing had been disconnected that would cause this, and everything that should be connected is. Fair enough I thought. However after 20 miles driving the problem was still there. The slightest touch of the accelerator causes the engine to cut out when the pedal is released no matter what rpm it's taken to. Even taking the revs up and very slowly releasing the accelerator it still cuts out. Basically once I've pressed the accelerator pedal no matter what I do it cuts out. It starts and runs at idle ok.
After a trawl of google I found a few possible causes (T-piece, idle speed control valve) the T-piece is fine but the valve is beyond my capabilities, however there was nothing wrong until the clutch was changed. Initially I tried re-setting the ECU by disconnecting the battery for ten minutes and then starting the car and letting it idle for 5 minutes, this did not work. After a further 30 miles of driving and having to restart the engine at every junction I decided more drastic action was needed.
A working solution was to 'adjust' the accelerator cable, I've pulled it out of the adjuster as far as it will go and locked it there with its clip, the throttle flap is nearly closed but not quite. The idle speed is normal and it no longer cuts out. However the car is a lot more lively now, the smallest press of the pedal now gives the same as a 3/4's press used to, I've not adjusted the cable that much!
Was incorrect cable adjustment the cause of the problem, have I created more problems by this adjustment or will everything be ok now?
BTW 165,000 miles on the original clutch, being used as a taxi, and it was the slave cylinder that had gone, plenty of wear left on the linings, is this a record?
