Changing the air filter might be a start.

Hi try some diesel engine injection cleaner: quote: Partially clogged fuel injectors can cause engines to lose power, produce excessive smoke, and experience a loss in fuel economy, Injector Cleaner is specially formulated to remove deposits from the fuel system of diesel engines. look for a good branded one , the one i use is forte i think thats how its spelt, its not cheap but if you can find it use it,cost about £20 a bottle, put whole bottle into fual tank with full tank of fual , should sort it out .

good luck

Take the air filter out and take it for a good thrasing. Get the engine warm, leave the filter outtill the test is finished.

Thanks gents
Ran some FOREX through the engine as an additive to the fuel and reduced the emissions from 5.6 to 2.6 inside the required figure of 3. As an aside the local dealer now recommends this is added as part of each service interval.
