1990 Safari TD42

Just the last few days my Nissan has done the following.

1. First thing in the morning it starts fine, runs fine
2. After about 3-4min it starts to lose revs and power and miss a bit. Smokey when rev'd
3. After another few minutes it runs smooth again
4. Starts and runs fine for the remainder of the day
5. Next morning - go back to step one!

Strikes me it's a fuelling issue. Any ideas?

what color smoke?

picking either partly clogged fuel filter or air being sucked into the line.

I was thinking the fuel filter as well - especially due to that exact timing each morning. Might be an easy place to start.

Do air filter also, get it breathing and drinking properly.

Thanks team. New fuel filter, new air filter and all is good.
