Lately I noticed a slight ticking noise when pulling off calmly (from a stop light, for example) at the exact moment the car starts moving. Happens when the engine is still cool, before I hit the highway, don't seem to notice it after that.
I've never heard an actual detonation so it's hard to tell if the sound is that or simply the rubber mounts or something (weather is currently cold and there is creaking in the suspension when driving over speedbumps). I might have some vacuum leaks. Is it possible for the engine to detonate while still cool at a regular slow pull-off?
