As I pulled into my parking spot today, I reved my engine. Instead of hearing the typical lifter tick, I heard a different sound. I checked oil levels, pressure, blablabla.
I can only hear it when inside the car, with my windows up. If the windows are down, it is drowned out by the sound of the engine/exhaust.
It increases in speed with the revs, just like lifter tick would. However, this seems to be coming from behind my radio. The only thing in this general area, that I know of, is the ECU. Why would it be ticking?
I'm pretty confused. Any helpful advice will be most appreciated.
