Hello,

I check through the OBD the cylinder 3 balance is 1.20-1.30 when the engine is idle (sometimes it goes 1.13-1.18), I notice the car vibrates at idle when the engine is cold.

Does the injector need to be replaced? Or can I continue driving with these values? Could the engine be damaged in the future?

I recently changed the injector washers (the cylinder balance value was the same before the replacement). Perhaps the ECU needs to relearn if this was the cause of the problem?

I also have an acrid odor, especially from the muffler.

Thankyou
