thank you so much for your details info and so nice of you brother showing concern's...
well let me know tell you my car spec below and what ever i've done so far to ensure top notch but unfortunately didnt succeed in it..
i've changed oil last month ZIC..
spark plugs has been replaced to denso ( mechinic said its also very good for idsi )
its on petrol and manuel since the first day.. also throttle body has been replaced already mnth ago.
i always changed my gear below 3000rpm..
so the thing which mechinic didnt clean was fuel injectors because it was dark at that time so he said come another day to clean them aswell.
my odo shows 138000km done.. totally patrol..
need your opinion now and please also share u hv mentioned about fuel filter changed how much it would be costing me.??
early reply would be highly recommended.
Thanks
