During starting or under load is their any excess exhaust smoke that you see? if so what colour?
Any warning lights come on since or prior to the fault you have?

Hi..there thanks for your reply..
Ok..the most logical thing that would be tried in such situations as this seeing as you havent listed it being replaced would the fuel filter.its possible if the filter is restricting proper fuel flow you would and can have reduced performance issue and redex in the system wouldnt solve that..so it maybe something to try a fual filter on the van and see how that goes..if at all possible too whilst the filter is being changed is to maybe have the fuel lines blown back to the tank..this just ensures the fuel lines from the tank to filter etc arent blocked..another could be fault with actual pressure delivery from the pump which ideally has to be checked with proper equipment or diagnostically to see pressures are within spec..also double check there are no signs of fuel leaks etc..also check the small vaccum lines around the engine are fully connected especially around the intake/egr valve system where the intake tube connects to..so as above if it hasnt been done upto now then i would try a new fuel filter and fuel pressure test..I do hope this helps
thankyou for your advice.regards wendy
