I have a Vectra C 2005 Life - Z18XE - I have been having a hesitation problem when cold, wont pull away properly. I have heard the EGR valve could be at fault but during my search on the subject I keep getting conflicting reports that the Z18XE does/doesnt have an EGR. Does anyone know what the case is?

Around since the 1970s - Vauxhall have had plenty of time to get their act together on these.

I know nothing about car engines but these links will convince you that your car does have an EGR valve - otherwise it would fail emission tests...
