radio has a hum whistle sound that changes pitch with throttle activation but sometimes it is not there at all.
Might be an alternator noise but not sure what is causing the issue.
I added a extra ground to engine block as a test but did not fix the issue.
Engine has a slight miss but there are no codes in any system.
Next step is a regular tune up plugs, wires, maybe check out coils.
Installed a crux BTGM33 bluetooth device which is completely plug N play no splices at all.
I thought that might be it but I removed it for testing and problem remains.
Are there any noise suppressors that actually work?
Radio noise suppressor or full electrical system that connects to the alternator wires?
I do see some on amazon etc. but reviews are sketchy
Any thoughts on this are appreciated.
vehicle has navigation and bose system
