Since I bought my Nissan Sunny 2004 ... Till now I still cannot drive my car peacefully...After I warm up my car ... And move car.... Suddenly starts vibrating and turned off automatically... And when I stop my car on signals Engine stop...To avoid engine off I frequently rotate (d) to (n)...I have shown my car to various mechanics in Qatar.. But they could not solve this problem..If some body knows especially the team of this website or company... please find the solution
