I been trying to diagnose a ticking sound ( like noisy injectors ) for a while now that starts atbove 2200 rpm. It is very pronounced when sitting inside the car under a load. When under the hood reving it passed 2200 rpm all I hear are the injectors. The car runs and idles good, I did a search on what a broken valve spring , stuck lifter and spun bearing sounds like and nothing seems to match the noise I am hearing. It's very anoying. Any ideas ???? Thanks, Kyle.
