@LOGAS,
Brother thank you for you kind reply.
I do beleive that Mr. Khatak is a nice and honest gentle man.
But my confusion is still there:
Car was fine from Islamabad to Lahore.
It was again fine from Lahore to faisal abad.
fine from Faisalabd to Islamabad.
fueling was only done from motorway and lahore or Islamabd.
When I reached Islamabad, I took cng form peshawar road. the problem started. And it was so severe that it was not possible to keep the engine running even with full pedal.
Thank you.
