Re: I need help

Welcome to the garage.
Seems that your idle control is not working well. Remove the IAC (idle air control) stepper motor from the throttle body and clean the plunjer and the complete air canal. Do not turn the plunjer head, because it will break the internal stops. If this doesn´t help, then its probably the TPS (throttle position sensor).
