Saturn Repair Problems? Ask a Mechanic for Answers ASAP
My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
With what you have described since it affects the cruise and the driving of the vehicle this is either a fault with the ECM (engine control module) or the vehicle speed sensor itself.What has to be done here to help determine the cause is to have the fault codes read out.If you can get the codes read out this will help.In some cases a local parts store will read out these codes at no charge to you.If you can get the codes read out and post them here let me know.
Since it does occur at a stop as well I am leaning more towards an issue with the ecm as usually the vehicle speed sensor will only act up when the vehicle is moving.
