Low on power

Hi I have owned my fiat sedici 1.9 diesel for a 12 month but last week she became very low on power when pulling off until the revs build up. I clean the EGR which was all sooted up and it have made an improvement but itís still abit low on power to what it was there is also grey smoke when coming from exhaust when I rev it up which it did not smoke before...any advice I would be grateful...thanks Fred

Re: Low on power

Check boost pressure. Sounds like it has trouble maintaining enough boost when the ECU cranks up the injection (grey smoke = unburnt diesel fuel)...
