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.
When exhilarating to clime a hill at 40to 50 mph the engine starts missing. on 2000 Buick Park Avenue
95% of the time it's the plug wires breaking down!! Scanner with misfire data and an ohm meter will find this problem!!!!
Thank you very much we will give that a try.
