On my way home from work, today, my Fiero lost power. At first, the engine was still running, but I could not maintain my speed. I shifted to neutral, and could still rev the engine, but it was not running wrll. As I cut across 3 lanes of traffic, heading for the shoulder, the engine died. I cranked the engine, pulled back onto the highway, and drove home. At the time of the incident, I had about 20 miles on the tank, and I drove about 11 miles home. Any ideas, or is this still the loose tube on the pickup idea?
