Been meaning to ask about this for some time. I've only noticed it when warming my car up, but I guess it could do it off of fast idle, just never noticed. Anyway after first starting up, every few seconds I hear a click, like a relay tripping or the air conditioner trying to turn on (which isn't on, and doesnt work very well either). When it clicks the idle bumps up a little and settles down. Anyone got an idea as to whats happening? Does it everytime I start it up, and has for as long as I can remember.
