I own a Santro Club 2004. From last couple of weeks, its engine find it hard to get sustainable RPM on idle. Car vibrates and so its engine, very visibly on idle. Some times it turns off while idling. However, it is not misfiring. After drive of about 10 to 15 KM when car is hot, it turns off on every traffic signal I stop. And after this, most of the times car do not even starts again on CNG and I have to drive on Petrol.
I have to keep pressing race paddle to make sure it don't stop.
I got this car checked from at least 5 different mechanics and every one have its own story such as..
1- Weak Coil
2- CNG Wiring Problem
3- Faulty Fuel Injectors
4- IAC Valve problem
All of them did settings and changes but none of them was able to diagnose actual problem I already spent too much on this and in return I am getting nothing.
I am really looking for some PakWheeler to tell me a good mechanic in Karachi who have Santro's scanner and can fix my car.
