Engine Performance problem
2002 Chevy Astro 6 cyl Two Wheel Drive Automatic 150K miles

When the engine is cold (eg; sits overnight) it starts immediately when the ignitiion is engaged. Once the engine warms up, it cranks 5 secs + before it fires up.
A complete tune up was done at 100K (new plugs, wires, distributor cap).
Any suggestions appreciated.

Pull plug check gap if more than .005 wider that will cause delayed hot start
