A family member recently purchased an Alto 2005 (used) and after a couple of months is experiencing sluggishness. The sluggish performance can be noticed outright while driving the car, and is present on both CNG and petrol (but not so much on petrol).
They had the tuning, oils, radiator and wiring checked... however desi mechanics could not locate a problem. The things that have apparently not been checked are thermostat (dont think it needs to be) and spark plugs. Would anyone know other points of concern that we should check?
Can someone please recommend a good mechanic in Karachi?
Would it be wise to take the car to Suzuki Motorways for a checkup?
