Strange Alarm thing (hopefully you all don't mind long posts)

[97LSi004]

I am going to describe this problem exactly what i did to encounter it. Basically my horn beep when i drive sometimes when the alarm system is connected and the security light always blinks even when i am driving.
My SVX, new to me about a week ago, had a blown fuse (four way flashers) which also controls the alarm somehow. When i replaced that fuse, i reprogramed the alarm and everything was hunky dory..
Anyway, i pulled the codes and got a knock sensor. i thought the sensor wasn't bad, because gas mileage is very good (at least for the SVX), and performance is fine, as hard as i pushed it anyway. So i did the whole, disconnect the ECU system to make it relearn, and i found that after a few hours the light reiluminated, and gave the same codes (after i got over to autozone)
Now, i haven't reprogramed the remote since leaving the system disconnected, because it usually still works. But the security light blinks all the time, and the horn sometimes beeps when i drive.. very randomly.. like once or twice and then wont do it again.. and it sounds like the doors try to lock or something sometimes.. VERY wierd.. so right now my alarm is disconnected in the trunk.. Do i possibly need a new alarm box? has anyone else had a problem like this?
Thanks for reading it all if you did.. haha, if not i don't blame you.. i just like to describe things well..
