Bhai, in gulshan, Go to Block 5 near Shan Hospital,NIPA if u have seen Optical shops, just before that 1 road is going inside(At 1 corner u will see car showroom,on other corner there is Tyre shop).
Just after entering in that road, 4th shop on your left after car showroom is AUTOXPERTS.
They have advanced scanners. Get your car checked once from there.Clearly tell them that i need to stop this missing otherwise i will not pay u
whatever sensor issue or plug wires or plugs, it will come in your diagnostic report.
Also get your cng kit and cylinder both serviced by them.
During tuning,always check your car with these parameters:
1. On petrol, without a/c, without headlights
2. On petrol, with a/c, without headlights
3. On petrol, without a/c, with headlights
4. On petrol, with a/c, with headlights
