On a stock Chevy Trailblazer ss you will get about a 5.7sec 0-60mph. I added a tune and an air intake and I am getting about 4.8secs 0-60mph.

Needs a PCM flash or tune. www.pcmforless.com
Typically,spark plugs, fuel filter,air filter and of course an oil change. There are no wires or distributor caps. If you have a misfire(then it may need a coil pack) or run ability issue then i would say to have the code checked.
Could be in need of a complete tune up.
