Hi guys please I need help ? My Nissan has been to two Garages and after a lot of buy this and buy that and replace this and replace that. Its even worse off than when I sent it in. It started off, on idle it would hunt, revs would go up and down, and when you would accelerate it would be like it has a flat spot first dip in power then pick up speed. And then I noticed that when you coasting saying in second gear with your foot off the clutch it would jerk and jerk. We changed the fuel pump three times, injectors were serviced and two found to be faulty, distributor was serviced and the coil replaced, new HT Leads, new fuel line hose, Replaced the MAF sensor but only could get a second hand one.
Please if anyone could point me in the right direction where I can start and see from there.

Many Thanks
