Strange surge

When my windows are all the way up and I'm sitting with the car on not moving, if I pull both buttons up to trigger the automatic close my rpms will drop like 250 and it will vibrate for an instant. Any ideas why it would do that?

Get your battery tested under a load. If your battery is weak it will draw harder on the alt. and draw the engine down. It could even be just a bad cable connection on your battery. A lot of times the connectors will look good and clean on the outside but when you pull them off the battery post they will be black or corroded on the inside. I hope this helps. It's a good place to start.

Def sounds like a battery problem.

I haven't changed my battery bought it back in 06 new...but I know it's leaking because of the residue that's building up on the top near the negative terminal. I have 130,000 miles, but I also live in California.

Now that I said what I said it jinx'ed me. Battery died...damn you! Hahahaha. Time for an optima or deep cycle. it won't even hold enough of a charge to turn the car over. Ps windows went crazy before it died im sure I'll have to do the window button trick after I get the new battery.
