Subject: Re: [worldcruising] More about diesel could it be air

I had a similar problem a long time ago and it ended up being a blocked /
dirty air filter which at the time I thought was a fuel related problem. The
more the engine tries to rev more air is needed, once it starts to block the
problem gets worse very quickly as the air filter sucks in on itself and
closes the air passage ways. Like all good things we need good clean air to
work well. Hope this may help
