Were you having issues with idling and misfires for some time before you replaced the coil packs and plugs? If that was the case, you were sending unburnt fuel into the exhaust and catalytic convertors. I ask this becuase if the fuel did go into the exhaust youcould have clogged the catalytic convertor. By lack of power do you mean you can't go over 20-30 mph and the engine bogs down? After you drive it , look at the underside of the car, the catalytic convetor will be glowing red, please do not touch, or you will burn yourself!!!!! This is a sign of a clogged cat. Please take the car into a garage/local mechanic to diagnose and repair your issue.
