I see my truck idle at about 600-650 rpms and at those rpms it seems to run a bit rough. Condition happens throughout the day no real specific time to pin point. I have also been seeing my check engine light come on when the truck is warmed up or it is warm outside, the check engine light stays on about a minute then goes away. I am not able to go to a mechanic so was just posting to see if anyone had some insight. Thanks for all the help in advance, really enjoy being here!
