Customer: replied 4 years ago.

nothing has been repaired two garages did a diognostic check no faults found the gearbox oil was topped up and the fuel filter checked

Ok the issue that you are describing is a fuel restriction,this can be from a weak fuel pump or a failing fuel injector. What I would suggest is to have the fuel pressure checked and s balance test performed on the fuel injectors.

The last garage checked the fuel system it it ok i can drive the car for 30 miles without it stalling or the engine missing it drives fine it,s only when i slow down to stop it feels like it is not changing down the gears and it stalls if i knock it out of drive it keeps running

Ok the fuel system will check out fine if the garage checks the fuel system while the engine is running normal. I would still recommend a balance test and a smoke test on the fuel system.
