Two different vehicles, same problem. My 86 GN with an aftermarket CD radio and my 90 Chevy K1500 pickup with the factory stereo, both have the "ticking" and high-pitched tone.
From doing a search, the primary causes seem to be:
-- bad spark plug
-- bad spark plug wire
-- bad ground
-- bad head/amp unit.
To fix the noise, should I ohm the plug wires first, then if they are OK run a dedicated ground to the chasis? How can I tell if a spark plug is the problem?
Any other steps that are recommended to fix the ignition noise?
Thanks,
