Greetings to all! I am the proud owner of a very nice 2002 ML320. I have a concern right out of the shoot. My wife was driving yesterday and the engine started to sputter, the check engine light came on and it seemed a bit slugish. This is all second hand. It was a very hot day and the air conditioning was running hard. The light remained on for some time, 100 miles later, and after she filled up with gas, she had a half tank, the light eventually went off. The engine temp remained in the good range.

This happened on another vehicle I had when the gas cap was not seated properly. I am a bit concerned that this may not be the case here. I hate to bring it in, but yet I am very concerned.

I am hoping that someone could give me some insight into this. I understand that it is not a lot of information to go on. I could always bring it in the see what engine codes show up, but I would like to avaoid the $100 bill out of the shoot if I could. If it happens today, it goes to the shop. Any advice???

Thanks,
Mark
