2 weeks and..

I've only had my truck two weeks and I have a problem. I went to pass someone the other day, stomped the gas, and when i stopped I felt the idle was not right. It would surge between under 1000 to over 1000, and felt like it was revving even as i was slowing down, and at red lights felt like it would stall. the check engine light went on shortly after. dealer says just a sensor, lets hope so

sounds like it could be a vacuum leak. i'm not too familiar with my engine bay yet but from my experience with other cars that's what it sounds like to me.

they replaced the mass airflow sensor, runs great now, hopefully it stays that way
