Hey Guys,

I'll be driving along right after starting the car and I'll hear a metallic kinda whack from the back right of the car. Normally I don't notice any difference in the way the car drives when I hear the sound, but today I felt a momentary hesitation from the engine when I heard the sound. I'm around 2000-3000rpm when I hear it. It's happened about 3-4 times so far in the last week or so.

Could it be detonation? I'm using Sunoco Ultra 94, so I doubt it's detonation. Perhaps the suspension? I have no ideas!

Does anyone have any ideas? Thanks in advance!!!
