Report "99 Isuzu Wizard with a 4JX1 Engine (3.0 Diesel Turbo) which has done 160,000kms. It all started sadly. When I started the vehicle it was like it was missing or running rough at start up, and only idled, even with full throttle down. When I went to take off, the engine has no power even with the throttle down. It would get better as the engine warm up. But it would surges and lag, struggle when driving it on the road. It has been like this for about two month. Now the weather has got cooler, I tried to use it and it wouldn't start at all. I really need some help to work out what is wrong. Can any one direct me to correct solution, I would be grateful"
