Report "Sometimes check engine light comes when I start up, but if I shut it down an start over it will stay off. Now last time I drove it , and within the first 5 minutes, it was going on lightly, then stayed off.I have owned it for 1week now got 110 miles on it, now this starts. It runs fine, no change. Put new plugs in last night, an added injector cleaner to fuel, see how it's acts today"
