Thats ok, I think everyone has helped, reading back through the posts. Its so difficult to diagnose a unique problem on a forum without the car in front of you. Common faults are much easier to diagnose remotely. Hey, even mechanics and a citroen dealer couldn't suggest much, so its going to be difficult, as in more than one fault. 2 or 3 things not working can make it very tricky to sort out. As the time went on, more and more information showed up.Thank you so much for all your help.
its the most help i have had so far.
A lack of power can be cause by many things, but reminds me of driving a worn out IDI diesel without a turbo. When all the other things are sorted and its still short on power check the waste gate and turbo but only after the crank sensor and vacuum loss are done.it is like driving a 1.cc engine gutless slow build up of power on hills.
Did they remove the injectors to test them? There are companies that can test the injectors off the car, there is no point replacing them is they are ok, but you can't really test them fully on the car.They said injectors seem ok on there machine but they think i should replace them anyway because they might not be ok.
This company will test bosch (1.4 HDi 8 valve) injectors and Delphi (1.4 HDi 16 valve) injectors
