Also I had my scan tool plugged in it was detecting I was going only one or two miles per hour when I took my car for a test drive sooo.I don’t have any feeler gauges yet so I’ll I don’t know how I can measure it but I do know the v6 engine was swapped with a v8 so maybe the ac leaked out or something I can’t be sure and that’s maybe the cause. Also the radiator fluid is clean and I’m not sure what you mean by an air dam?
