HELP! Hi. I have a 2002 2.5 Turbo diesel Pick up. I think its the 4JA engine.  It has done 100,000 miles.  It has been looked after with regular oil changes. The last few years it has had very little use about 200 miles a month. Vehicle starts and runs ok. When vehicle has warmed up and a little more power is called for i.e. overtake, the power just seems to go and then it just starts smoking badly, sometimes it stalls.  Its starts up ok and everything seems ok for a few more miles then same thing happens.  I have changed the fuel filter and cleaned out the small gauze filter in the supply line to the injection pump, but no change.

Any Ideas please  

Thanks John
