after replacing the spark plugs, is it recommended to clean the fuel injections

What is your question?

Had my spark plugs replaced and recently for a month some time my car don't have that super charge taking off or up a small hill.

What makes this problem better or worse?

Better at first, but for a month now it has lost some of it super pick up and go charged.

How long has your 2007 Toyota Avalon had this problem?

Recently for about a month.
