Hi,I’m new to this forum.Thanks for the add.
i have a strange fault on my 2009 Onsignia A18xer engine.
When starting the engine runs for a couple of seconds before stalling.It will continue to do this no matter how many attempt you make.
After days of trying to get to bottom of problem I noticed if I disconnected map sensor it would start and idle perfectly all day.If I connect map with engine running it will stall immediately.If I disconnect again it will start...
If I connect map and disconnect intake cam soleniod it will start and run perfectly and can be driven.
if I connect solenoid when running engine stalls and will not start until disconnected again.
If I connect solenoid and disconnect intake cam sensor it will start and run perfectly and can be driven.
If I reconnect sensor when running engine it continues to run
and will do until I switch off but will not start and run after this unless I disconnect one of the above sensors.
When all connected there are no fault codes recorded.
when running the engine sounds sweet as a nut.
I have spent many hours just to get to this point .
Any ideas would be appreciated.
Hope this reads ok
thanks for reading
