Question about 2000 Mercury Grand Marquis
I'm having some troubles with my car. It wont keep an idol, but it still runs when in gear and driving. I replaced the battery but I'm still having problems. I always leave the light switch turned on and I'm wondering if that could be causing some problems? After driving for approx. 5-10 min depending on the weather, the car will keep an idol but it is very faint and you can barely hear it running. When it is really cold outside its extremely hard to get it running and when its warm it still has a faint idol and isn't running properly, but it is easier to get going. If you could give me any advice regarding this issue that would be awesome. Mainly I would like to know about the light switch draining the battery. Thanks!
Yes, any electrical device left running in car will drain battery, not unless you are running the engine for it will continue to charge the battery, regarding the idle setting issue, have a qualified mechanic check and adjust your clutch idle setting to fix your problem.

SOURCE: My battery light is showing
Here is a procedure to isolate a battery drain I found elsewhere and has already proved very useful several times.
Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or “light” if there is a drain. If the “light or glow” is faint, that is probably normal draw for the clock or computer. If the “light or glow” is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. ***Remember to hold in the button in the door jam for the interior lights.***

Have a mechanic take a look at your throttle position sensor and engine idle sensor. Make him manually adjust them as opposed to just putting in new ones. It may require that you have to have a higher idle than normal. Your underlying cause is going to be that I am sure you have a lot of miles on your engine.
