sounds like a bad battery

Run a thick wire straight from the battery to the positive terminal of the horn. If the horn sounds normal, replace the relay. If the horn is still weak, locate the adjustment screw and play with that to try improve the tone, if that does not work or if there is no screw, replace the horn,

It sounds like you are getting a weak spark to one or more cylinders. I would start by checking that all of your spark plugs are connected. Make sure the plug wires are in good condition and connected in the proper firing order. If applicable, check your distributor cap and rotor for damage or wear.

get a 12-volt tester and check the wire going to the horn to see if there is power going to the horn if it is the horn maybe bad check all fuses first i hope i have been some help to you Michigan man.

my jeep was just having that same problem make sure the battery cables are tight and have no corrosion,doesnt sound lik a big deal but it is,and check the carborator and air filter, it may not be getting enough air flow
