Thank you Bro, for ur detailed replies, actually i wanna sell out the car and wanna get a bigger one, so is there other way except replacing the parts? i mean if it just gets better by cleaning the throttle body? or doing some other techniques? and from where can i get this? should i also go to Toyota Motors at Karachi?
and yes another question bro, with this problem was ur car use to get heat up so much? mine does a lot like the bonnet inside thing gets warm like an iron, but it doesn't show heat sign at dashboard, so is it common with these 660 cars? or this isn't normal thing?
