for mr.munna bhai .back fire is the common problem in baleno.because the air filter is not designed well.to avoid back fire close the filter box tightly as u can and get it cleaned and changed on time and just buy A grade filter.secondly ur rpm is moving due to throttle body get it cleaned by a mechanic.and adjust the rpm censor.and to increase pick on ac it is also a baleno factory fault but it can be handled by increasing the gas supply.otherwise on gasoline it will run perfectly.
mr jazy get ur throttle body cleaned..sometime there is carbon in throttle body and adjust rpm censor these are common problems in balenos model 2003 and onward are exellents cars.baleno is a nice car wid little different problems but can be handled easily.so drive and enjoy.
mr.waqas u have to pick baleno in 1st gear when u accelerate it more then 2rpm on ac other wise it will switch off.and to increase pick install A quality plugs of denso these are good for suzuki and check ur ammulator and advancer and also get ur car tunned by some experienced mechanic.
for alll baleno users avoid to wash ur car engine from service station and avoid the car engine from water.other wise the car will be hooked up and will disterb u very much.the "patakha" problem in baleno is due to same reasons due to water vapours in coils.other wise coils kharab nahin hooten.aur agar kisi k saath yeah problem ho gaey tu dont need to worry.only buy kabli coils not new one because some times the genioun parts are not genioun.only kabli because suzuki k show room say bhi complaints aa rahi hain B grade parts ki.so install kabli coils they will cost between 7000-16000 depends on condition.and for all users avoid buying 99-2000 baleno because 60% cars in this model have facotry faults.so 40% main ana risky ho ga.buy 2003 and above model these are really good cars.
