hi mark..thank you so much for your reply....yea..it gives out black smoke...after i run it for around 2 minuts...i even got it checked with one of my fellow mechanics..but he couldnt diagnose it properly...he checked almost all the normal causes but couldnt find the exact reason behind....he also told the engine compression is bit low too...

have you run a diagionstic code, i have seen faulty MAF sensors cause this, a scan will show up any unresolved fault codes, do this next.
