Idle surges
I noticed that my idle surges when I am stopped at redlights and other times when I'm the car is stopped in Park, Neutral, or Drive. It goes from the normal 600rpm's to 500 for a second and then back. Feels like a very slight stall. I cleaned the throttle body, MAF is ok, tune up, new fuel and air filter. I thought doing these things might cure the problem, but it's still there. It's not major but annoying as hell. Any ideas what it could be?

I experience the same thing. Sometime it happen, sometimes it doesn't. But when it does happen, I am stopped and my foot is on the brake. When I let off the brake it stops. I was told this is a vacuum problem caused by a leak in the booster which affects the vacuum controls on the engine

Just another option to look at anyway.

That might be true, but my battery is only a year old. Could it be that I have two amplifiers hooked up to the battery for my sound system? Could that affect the rpms and how would I test the theory of the battery and altenator?
