Cars Q&A

I am Anson from Kochi. Kerala. I have a 2004 model Zen diesel and facing a missing problem now and then on cold starting. There is no starting problem but when we start to drive, have to face unbearable missing OR Jerking. In such time there will be white smoke and bad smell like incomplete burning of diesel from exhaust . After 1-2 KM of dive actually it will not just drive but jump every thing will become smooth and if we stop the car and restart again this problem wont appear again at that point. I have checked heating plugs and fuel injectors with several mechanics nobody could not find the reason. Please help me. mob:9388950066
