Some times a quick hiccup will turn on the check engine light and after a certain amount of start ups with out the problem reoccurring it will turn it out. So they do kind of fix themselves.



My 2003 hemi ram 1500 (88,000 miles) will do that from time to time. It will be hard to start and then run very rough for a few seconds. Then all is good and the check engine light comes on but after a few more starts it goes off.
