Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello and welcome!My name isCustomerand I can assist you with your question.
The most common cause for this high idle condition is a faulty TPS or idle air control valve located on the side of the throttle body. Both are very common.
Another possible cause would be a faulty engine coolant temp sensor sending an incorrect signal to the PCM causing this rich running condition and possibly the higher than normal idle.
Also, be sure to check for air/vacuum leaks under the hood before replacing any components.
I am glad I can help!
