Q: Idles Low and Almost Stalls

asked by on February 22, 2017

My vehicle has been idling at 500 and below and is bucking or sputtering when at red lights or in park. I have a faulty coolant sensor that yet to be replaced as I would have to replace the entire coolant reservoir. Would this sensor be causing a low idle issue or what else could be causing this?

My car has 110000 miles.
My car has an automatic transmission.
