I have a 1986 Chevy Camaro, 2.8L V6, when stopping at a stop light or sign my car stalls. Sometimes I get a rough idle when stopped. This happens in hot weather when the car is also hot. The car is not vapor locking because the car starts right away. I have changed the MAF, Oxygen sensors, Distributor cap and Rotor, new plugs and wires, and new air filters. Does anyone have a clue?
