Dear Baleno Master, I have a very well maintained 2003 Baleno JXL driven on petrol when bought zero meter. It has clocked around 149,000 KMS. The problem with it is that it is giving jhatkas on 2nd gear mostly when it is at slow speed. My mechanic is outclass, he told me to use hioctane and fuel injection cleaner. I have used that and this problem finishes but when i stop using hioctane and injection cleaner. The problem comes again, do i have to open all the fuel injectors. Will it be just cleaned and the problem gone? Or will it be changed with new ones as new ones are very costly what do u suggest?
