I have been driving my 93 Z28 alot more this summer/fall and have noticed some issues that I am hoping my data log will be able to identify. The car notoriously runs rough when its cold after sitting overnight. After the car has been ran and has a chance to sit and become heatsoaked, it will run much better. My mileage has also been right about 15 mpg with a mix of city and highway driving. I pulled the data log tonight that is found at the link below. The car was started in a much warmer garage, then driven at approximately 40 mph for a short time, then I got on a tollroad and drove it for a few minutes at about 75 mph. Can any of you look over the data log and see if any issues jump out at you?
