Second owner original owner serviced it at the place I bought it from..... All regular servicing It was their weekend car. I put new k&n drop in filter about a month ago. Still on duelers running about 38psi... I mostly drive highway at about 60-65mph and dont race or over accelerate... Other than guzzlin gas at an exponential rate everything seems fine. It doesnt smell like its running rich or anything. Ill just have to find some time in my schedule to get it in and looked at. They probably wont find anything anyway..........
