Thank you, very helpful response.
i thought about tuning a month ago but my colleague told me not to do chher chhar with this car because ek baar tung kia to phir tung hi kare g.
i am not a regular at driving. have this vehicle for 25 months and have only driven 3400 km.
Should i take it for tuning to resolve the issue? last tuning was done in november 2015 since then its done 3000km.
apart from normal cleaning and gap of plugs etc., tuning wala uses exhaust gas analyser to check carbon emission of the car and then make some adjustment. has that something to do with throttle?
