i own a repair shop,and its may need the timing set on it,,timing is where a car gets it power from,,if its off,its not going to run right,,and also have the catalytic converter checked on it,when these get bad they,ll cause one to loose a lot of power,,i think the majority of your problem may be in the timing,,if it has a lot of miles on it,,that chain,and gears may also be worn down bad on it and it may need replaced,,if their worn bad,,re-setting it will help,it a little,but replacing the chain,and gears will really bring it back to life,,good luck hope this help,s.1993 Buick Century 3.3L - Will not start, has new battery, altenator, and main computer...?
