Yesterday I advanced the timing a little on my pretty much stock 1gen Integra (it felt more sluggish than normal, and its normally pretty slow) , and went for a short drive, it ran better, but when I popped the hood, there was a noticable increase in heat in the engine bay. I've never seen that before, is that a sign of a larger problem with my car? Any help would be appreciated.

Thanks.
