I took off from a stoplight in one of my more ease into it modes and the car coughed and almost died. The coolant warning light came on so I pulled over and checked oil and coolant. Both were OK. I started it up again and had the check engine light also on so I had it towed to Saturn. They said that the water cooler on the supercharger blew out. They special ordered the part for today and hopefully it was just a fluke. Any ideas?
