Outer Limits 4x4 Board

Im just wondering if anyone is having the same problem sometimes when i rev the ute or leave it idleing it will idle down to stalling point does anybody else have the same issue or no how to fix the problem,I Also cleaned out both tanks fuel lines put a new filter on and still doing it
Any help would be greatly appreciated

Cheers Ian

Sounds like you have an air leak somewhere... check all connections and lines for starters. It takes nothing to make a diesel do this ..
Or fit a lift pump at tank ! then you should see a small leak ..

Cheers mate will try that
