Am Radio

Another question. Does anyone have any idea why, when I have the am tuned on my radio, it has an annoying buzzing noise when I am stepping on the accelerator? Thanks.

It is probably the alternator or a plug wire going bad. Check the grounds on the vehicle and make sure the plug wires are firmly attached to each plug. As for the alternator clean the contact points where it grounds and make sure all connections are tight. If all else fails change the plug wires with new ones.
