Car backfires at low rpms

[CenturyTune]

Hey everyone, for some reason i noticed my car backfires and stutters at around 1.5 - 2000 rpm when i step on a gas about halfway, if i press it slowly its fine. Any ideas? Its non turbo. I heard it could be timing issue, i replaced timing belt in the summer but it started to do that no too long ago tho.

+1 to fuel pressure check and maybe check your plugs/wires.
