I have a 2011 Mehran. It was giving me 10km/l average so I got it serviced recently. I changed engine oil, air filter, got carburator cleaned and serviced but the car is still not giving good average and after driving for 5 to 10mins the engine begins to lose power and does not accelerate well. I asked around and from reading various posts on PW I think the issue might be with the ignition/Distributor timing. Can anyone suggest a good mechanic in Rawalpindi or Islamabad that can help me with this? I do not trust mechanics that just adjust everything without proper equipment. So any help or guidance in this regard will be appreciated. Thank you.
