Christian, I had a similar experience in Auburn, Indiana last year, which was quite unnerving since South Carolina is home. The car acted very sluggish and wouldn't take extra gas. It was pouring rain on the interstate, and I could only go more than 55MPH without the car sputtering. At first I thought the problem was the fact that I was low on gas. It ran fine after I filled it up. I had a problem two mornings later when there was a heavy fog all night. I continued to have this problem once I got the car home everytime there was heavy moisture in the air be it from rain or fog. It turned out that my distributor had a small crack and moisture was collecting inside the cap. A new distributor and plug wires and the problem was solved. Brian VIN 1597
