Hi Vikram

I may have had a similiar problem, when warm the car (89 200Q) would 
stumble and stall,  sometimes making a loud pop, but always starting on 
the second try, so I had the injectors pulled and leak tested under pressure.
They all required cleaning (not talking Techron here) and they returned to 
spec (I forget, like 1 drip ~ minute).  I thought for sure they would need 
to be 
replaced, but my mechanic said they looked fine (car has 106K).

I haven't seen the prob return, but it was cool today. Still the car felt a 
little smoother.  For $60 I can't complain, if I did the job myself I probably
would have replaced the injectors needlessly.

If the car cranks alot before starting it could just be a check valve that 
stops 
the fuel from returning to the tank.  In that situation the fuel pump would need
time to fill the injectors again.
