Glad to hear you didn't end up losing your ride. That'd suck for sure.

I seem to recall a device that had a switched input to the coil as well and if you didn't hit the switch within about 30 seconds of starting the car, it would simply start cutting out cylinders and the car would end up dying....The theory was, as I recall, that if a thief got the car started and then began to drive away and the car just started running rough, died and wouldn't restart (with out putting the hidden switch in the propper position), they would assume that the car had mechanical problems and would abandon it before they actually got away from the area it was in with it.

Good luck and hopefully you guys can catch 'em in the act next time they try it.

Cheers,
Dutch
