Great forum- this is my first post. I have a 1982 cross-fire. After I have driven 15 to 20 miles and come to a stop the engine shuts down. It restarts but runs rough. When it is first started it runs fine. It appears to happen after the engine is warmed up. The coolant sensor has been replaced. The car does not overheat. After it sits for a while it runs and idles smooth. Any thoughts on where to start first would be appreciated.
