Running a compression test or dynamic compression test is an important, but little-used and often overlooked engine diagnostic tool. Why is this test so significant? It can be used to pinpoint the cause of a misfire when all the usual tests return normal results. Doing a compression test, is a good way to measure the condition of, the rings, cylinders, and valves. So, if your engine is running rough or is lacking power, consider doing a compression test. Also, it is important to perform a compression test every time a tune-up is done, as part of preventative maintenance.
