I am confident the Mass Air Sensor electronic circuitry was being affected by moisture. When the MAS electronics were dry the car ran normal. Whether the MAS plastic houing was cracked by a technican working on the car or from heat build up due to 13 hours of high speed driving in hot weather I don’t know. I want to thank everyone for assisting with this problem. Tony
No suggestions, just wanted to let you know that I seem to have an identical problem with a 97 regal. If you find the problem please post under “stalling buick”
