Since I tightened the loose ground strap, the car now starts fine. However, there's a new problem: The coolant temp and fuel gauge are now both pegged at the upper end of the scale when I am on the hwy. When I'm stopped at a light, most of the time the 2 gauges are pegged but sometimes it jumps between pegged and normal reading.

Hey Tom, where exactly is the problem this time?
