Car feels slow

Car has been feeling slower lately than it used to. Won't spin second. Doesn't miss or anything, and has good oil pressure. Where should I start? Also has issues holding idle on cold start, but that's been That way before it started feeling slower. Thanks guys

When is the last time it was tuned up? i.e. spark plugs, wires, fuel filter, MAF cleaned?

Cleaned the maf a few weeks ago. Don't know about the fuel filter or plugs though. It is not throwing any codes. Should I start with the fuel filter?

Yeah it's easier to do. If the power doesn't return then I would look in to new plugs and wires.
