My daughter's 2018 automatic has lost throttle response twice in a week. The check engine light comes on. She pulls over left it running and a minute later drove off fine but with the check engine light still on. The 1st time I checked the code with a creader2 and with the key trick both so no code. The 1st time I was hoping it was a fluke so I erased the code and it happened again today. She was only home for a few minutes before she rushed of to work so I couldn't check for codes this 2nd time. Any thoughts what I could ivestamagate in the morning?
