car sputters when accelerating but idles ok and runs ok once get up to speed

Asked by for the 2000 Plymouth Neon
Sputtering on acceleration is usually ignition or fuel system related. Is there a Check Engine/ Service Engine Soon light on? If so connecting a scan tool to the diagnostic socket under the dash will show fuel trim figures if it is running lean for fuel or may show cylinder misfire count if the ignition is failing.
