The problem occurs on every hill. Took Buick to several mechanics and got several different solutions. From computer problems to transmission/tork converter. But know one was really sure.

    95% of the time it's the plug wires breaking down!! Scanner with misfire data and an ohm meter will find this problem!!!!
