My 2003 Toyota Matrix pauses before going when I step on the gas. It only happens from a stopped position or under 5mph. I replaced the spark plugs and it helped but it is still there frequently. Any help?

Bad PCV valve? Dirty throttle body? Could be any of a number of minor things. Let us know if there are any other symptoms.
