My Chevrolet optra 1.6 is reaching 2 years old. Recently my optra is behaving strangely. When i cruise from 0 to 80kmh at a near constant 2000 rpm i will experience shake and jerking from the whole car. This issue is not new. It will happen maybe every 20000km or 10000 km..
The culprit? Is the dirty fuel injector..
Solution? Simple go get yourself a fuel injector cleaner and pour it into the fuel tank..drive around for 10 minutes and it should solve your problem. But please take note, i bottle of fuel injector need to be added to the full tank..the ratio is 1 bottle of fuel injector into a full tank..get it?
Ok hope that will help other optra owner..
