Hi All,
First of all a big thank goes to everyone who pitched into help. For the benefit of all the cars suffering from the same issue as mine, I am posting the thing that worked for me.
After the last few engine stops I was dead scared to put the car on the road. I tried all sorts of re mediation such as, Engine tune up, Cleaning of fuel pump and fuel system,cleaning of air filter but none of them worked for me. At last I decided to change the Cam sensor. Took the car to a small garage and the guy there got me a cam sensor from one of his contacts.(This was a used one which was taken from an used engine sale) Cost me Rs. 6000 + 500 for the supply and installation. Its been more than 2 weeks now and looks like(fingers crossed) it had worked. But still when ever I get into heavy traffic my stress levels escalate
