I own a Vitz 2003 Model (CNG/PETROL) 120k+ on ODO meter.
Car was not running properly on petrol so mechanic claimed some cylinder or coil problem. After the repairs the car is running perfectly on both CNG and Petrol but their is a continuous tak tak noise coming out of engine. and frequency of tak tak increases with the increase in acceleration. Mechanic claimed that the sound will go away with time but their are no noticeable symptoms of reduction in noise since past 1.5 month
Check light on appears after 5-10mins of driving. The car recently had over heating issues and after repairs i feel like the fan is not turning on when it is required to be. it just turns on for like 30 secs and then turns off. Their are some traces of oil leakage as well from engine head. Is the check light and fan issue is due to some sensor issue?
Please guide and suggest me a reliable mechanic shop. i live near North Nazimabad Karachi. Is Shamim Autos near Gulshan-e-Iqbal reliable? i've heard that they are quite expensive. or Would it be best to take my ride to toyota indus motors?
