That tatatatatatatatatata sound normally you can hear from cars climbing hills on too high a gear.How do I describ ah....
Like tatatatatatatatatata. I had ask the mechanic but he didn't recommend me to adjust the teppet.
He say the car all running fine from his experience. If really one to adjust he say will have some power lost. Sorry for my broken English because hw saying in Chinese I had to translate.hahahhahaaha
