Kia Troubleshooting Questions? Ask a Mechanic
Hello, my name is Bobby. Thank you for the question. Most of the time this is caused by an issue with the crank position sensor. When it stops reading the rpm gauge will do this and the vehicle will run like this. Most of the time the engine will also stall, but not always. If it is not the sensor then it may be an issue with the computer. Since the check engine light is on you should start by having the computer scanned for codes. Most auto parts will do this for free. If you do this and bring me the codes I can tell you with more certainty what is going on.
