2005 SVE occasionally cuts out when changing down gears at

Resolved Question:

2005 SVE occasionally cuts out when changing down gears at junction / roundabout - first thing in morning will take maybe 2 or 3 turns of the ignition key ( it always used to @catch' first time, immediately ) and the tick over is uneven - it seems to rise and fall in a regular rhythm.
The garage replaced the fuel injectors a month ago and at first it seemed to have sorted the problem, but it is back to square one now.

Hi there, do you have the gas or Diesel engine?

Sorry, I should have said - it is a diesel

Thank you.

 

Sounds to me like you may have issue with air in the lines or with the SCV. This would also explain why replacing the injectors temporarily fixed the problem, because they would have bled the fuel system at that time.

 

The SCV is similar to a throttle for the fuel pump and controls the supply volume to the pump. For what it's worth, the SCV is usually the culprit with any fuel supply issues, the high pressure pump is rarely at fault.
