I have a 93 Honda Accord LX in great shape, gonna keep it for a few more years. It has a slight engine sputter from 2200 RPM to 2400 RPM. Now my mechanic just changed the timing belt and replaced some seals and gaskets, remember this baby is 21 yr.s old. He told me the timing was off 2 degrees. Would this account for the sputter? The sputter is less since the timing was redone, but it's there still a little. Does anybody have any other ideas what may be causing the sputter?
