Accelator pedal locked after changing battery

The throttle control on these cars is operated by electrical signal from pedal not traditional pull of cable. Try turning car on then disconnecting the throttle control module plug you can follow the wire from firewall near gas pedal up to throttle body near where plastic snorkel or intake hose connects from airbox to top rear of engine. Car should shut off after unplugging so reconnect and turn key off and on to attempt to restart if car now responds to depressing gas pedal your acceleration should be restored and car should be out of idle limp mode. If not may need to replace the throttle control module or inspect wiring for breaks melting splices pinches etc. Good luck
