Radar Detector problems

[RedlineRacer]

I changed my distributer cap, rotor, spark plugs, and spark plugs wires the other day. I installed them in the parking lot of Advance Auto, I started driving around, and my radar detector went off. At first I just thought a cop was near. But then I realized it was a laser reading. I have had a radar detector for a long time now, and in all my driving I have never had a cop track me with a laser gun. So, I kept driving all the home and it was going off all the way home. Then I started thinking that it wasn't a cop, and it was the radar detector, but then I noticed it only did it when I am around 4k rpm's. Has anyone else had this problem?

I've got laser and it doesn't do that on mine, I know that some cell phones, security systems, automated doors, grocery store scanners, etc will set them off though.

All of those will set it off on the radar band (either Ka, K, or X), not laser. But I have tried it everywhere, and the only thing I can think of is that my engine is setting it off. Cause I will be like in the middle of no where, on a back road. Then turn it on and it will go off right when I start to drive.
