It could be something simple as a defective or misadjusted throttle position sensor - but you would be better off to find someone with a TECH 1 scanner to check all the ECM parameters - assuming there are no error codes. Does the Check Engine indicator light during the bulb check before you turn the ignition switch from run to start?
