The popping noise from a Buick Regal could be one of several things. You could have brake issues, or some problem with the suspension. Left unimpaired, the car could break down at any time.
Some of the places a person can find Buick Regal parts are JC Whitney, Autoparts Warehouse and also from the Buick store itself. Another option is through a pick and pull company.

Moisture will be the cause for an engine misfire. Depending on the year of the car will have a bearing on the solution. It could be that the plug wires are misfiring due to dampness.
I have a Buick Regal LS and I had them run a computer diagnosis and it was due to the gas cap not fitting properly. There is an electronic sensor there. Most automotive stores will do this check for you free of charge.
