When I start my car, there's a hesitation and weird bumping around sound for about three seconds and then its gone. I replaced my motor mounts not long ago but I still suspect that it's the motor mounts b/c they're not new. I'm afraid that it could be a kind of engine relaated knock. There's a small hole in my rubber intake tube but the area typically covered by my battery, maybe some unfiltered air got in my engine idk. I'd like for someone to come and help me decipher what the problem is, I hope to God that it's something minor like a motor mount....
