Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello and tank you for your question,If the engine drive well off of idle and has its normal power the the timing belt is likely okay. The idle speed is controlled by the computer and if the battery was disconnected during the repair its likely the computer has lost its closed throttle values. I would suggest you disconnect the negative battery cable and then take some carb cleaner and a soft cloth and give your throttle body a good cleaning. After doing so, reconnect the cable and start the engine and allow it to idle of about 15 to 20 minutes so the computer can relearn the closed throttle values. Give this a try and see if it straightens out your low idle.
