Just a thought, could bad gas cause this. When I was in Columbus with the dog is filled up at United Dairy Farmers store and the smell from the tank and car was very strong and funny. My wife even ask if had spilled some on me. We could smell it from inside car going down the road. I figured one tank of cheap gas being ran out at 70mph that day would not hurt me. Was I wrong. Going to fill up this morning at normal station and put in super premium $4.29 a gallon.
