@KamranAslam @Sqamar lolzzz..
i was having some problem with my car... and due to lack of time.. instead of sending it to the 3S dealer i went to 2-3 road side mechanics everybody says a carb BUTTERFLY issue... then i went to mechanic with @sqamar he told me it just need setting ... however he also fails to do so ... @ that time my car started showing BATTERY light .. then we went for electrician .. he puts relay (which was not required... ) .. anyways ..
in short, we took in a car in a street where a nissan sunny was parked .. i didnt manage to judge the bumper of that car resulting scratch on left back fender and door pannel ..
which was not done by mandviwalla nicely !!! am happy with it ..
however .. mechanical issue there was just one grip which was heated up .. replaced with original car started works fine .. the relay put by electrican was taken out .. carb was fine ...
solution >> that faulty grip effecting performance of fuel pump resulting jerks on petrol .. which was diagnosed as a carburator butterfly issue
