Loss of power
I have a 2000 Bonneville SSEI and It starts great runs great. However going down highway when you give it gas like to go uphill or to pass whatever...It just seems to have no power whatsoever It also bucks and jumps when doing that. I test it seeral times and it seems to be fine when in park just does it when driving..even taking off and getting into the gas a little it does it. Any and all help on this matter will be great!
