Recently i have noticed my Altis 1.8 2006 is occasionally missing, it makes sound like BUR BUR BUR from silencer, but i think its coming from injector? maybe an injector is blocked or some direct in injectors?
Cas I m sure noting is wrong with the Silencer, as i replaced it last year with a brand new...
The missing goes away after some driving and come back after few days.. i have tried to put in STP fuel injector cleaner but doesn't seem it works perfectly?
So i just wanted to ask do i need to replace fuel injector or can it be cleaned or what else problem might be?..
