Hello, I am years of convinced Honda driver. I drove myself from the old CRX up to the new Civic. Now I convinced my wife of a new Honda Jazz, 50 years edition. 2012, 1.2 displacement, 90 hp, GG2 We have the car are about 5 days. Suddenly a metal rattle appears when accelerating, but only in cold condition. After about 15-20 min drive it is gone. And this happens only while driving in idle the noise is not heard. goods at Honda, mei a woman gets a rental car because the workshop wants to take a closer look at ours. She drives from the yard and there the noise is actually also at the rental car, also Honda Jazz, 1.2 cylinder capacity, 90 hp, GG2, 4500 km down. The mechanic says it is the injection valves that wobble there. And it is normal. I ask myself that this is really normal? My Civic doesn’t make these sounds and all the cars I’ve driven so far did not. Unfortunately, I’m not an expert. rejoice at your help and opinion.
