I have a 92 dx hatch and have had a b18c in it for three days. I,ve put about 250 miles on it so far. A few times when I let off the gas I heard a kind of pop. It sounds almost like a cv joint when they are going out but this has only happened twice. The other time was when I accelerated and let off then accelerated again. If I try to make the sound happen I can't. Is this a common thing with Accura drivetrains or should I check it out further. I jacked up the car today and spun the wheels by hand back and forth and there is nothing abnormal looking or sounding. Any ideas? Thanks.
