Hello, I'm new here. I have a 1995 chevy lumina with 90,000 miles when the car is driven 15-20 minutes it dies and it won't restart or if it does restart it does again until it cools down. The temp reads higher than normal and will show a low coolant light even thought it is full, the idle is high but sometimes it goes t normal then dies. I hooked up my scanner and noticed that is shows that the quad driver 4 shows that it's bad. Please help
