Hi Guys.
Over the past 3 or so weeks the VS has been struggling at start up from cold start and warm starts.
On a cold start it will take around 4 seconds to fire and then it will shake at around 4-500RPM to the point of almost stalling for around another 4 seconds then will be perfectly fine from then on....if I leave it for half an hour or so it will do the same thing again.
Any ideas?
I have cleaned the IAC valve, PCV valce & TPS Sensor, Replaced the CAS, checked for vacuum leaks, checked error codes...inlet manifold gaskets were done around 2 months ago
Thinking it could be a bad injector, they all seem to be pulsing ok....and the car still runs like a dream its just this starting issue that has got me puzzled, only other possibility that springs to mind is the fuel pump.
I have taken advice off a US forum and disconnected the vacuum line off the fuel pressure regulator to see if fuel spits out which it doesn't (which is good).
Bit stumped.
Any help tracking down the issue would be much appreciated.
