The job of your Buick Regal fuel injectors is precisely what their name suggests: to inject fuel into your combustion cylinders. Your Regal fuel injectors may be either mechanic or electronic. In most newer models, the Buick Regal fuel injectors are electronic and the amount of fuel they inject is controlled by your vehicle's onboard computer.

Most Regal fuel injector systems are multi-port systems, which means that the same amount of fuel is delivered simultaneously to each cylinder. Your Buick Regal fuel injectors are precision instruments, designed to deliver a precise amount of fuel to your cylinders in a carefully controlled spray. As such, there are a number of tiny parts like seals and o-rings contained in the nozzles of your Regal fuel injectors.

The most typical problems with fuel injectors occur when the nozzles become clogged with debris or grime build-up, and when the small working parts are worn down over time through normal use. If your Regal fuel injectors are not working, you may notice a drop in fuel efficiency, sluggish engine performance, chugging, or stalling out. When your fuel injectors are clogged, you can sometimes clean them with a fuel injector cleaner that is added to your gas tank. However, if the small parts in the nozzles of your fuel injectors are worn, you will have to replace the fuel injectors.
