Thanks a lot Irfan Siddique. Nice guidance.
I have contacted Honda for Keyless but they refused that this option canot be installed in I-vtec as Chip registration is not allowed.
I have filled one CAN of injector cleaner yesterday in fuel tank as I was comming back from Lahore to Multan.
I have paid 13.55 for this Car. No CNG is installed. Driven on petrol all the time. drove it about 900 Km on saturday and sunday. Enjoyed the drive and pick.
