Q: Service engine light only in warm weather
My service engine light has been on over a year. The code is for emissions. My mechanic has changed some parts but still.. it stays on. I live in North Carolina. Both last year and this Christmas I went to New Hampshire for the holidays. The light stays on here in North Carolina most of the year. But as soon as I am in 20 degrees or less the light goes off and stays off. For 2 weeks in the cold.. no problem.. as soon as I drove south again it came on again.. on the very rare occasion that it is low 20's or less in North Carolina, it stays off also
My car has 150000 miles.
My car has an automatic transmission.
