I've been noticing a clicking sound while idleing. I also notice when it does click the rpm's drop a bit, maybe 250 RPM's or such. Any idea what it could be? Maybe spark plugs? Something worse?

if it is this then its not a problem correct?

If the a/c system is cycling, does it still make big hits on the RPM's?

excuse the noobie questions, just a bit confused.

 

that is what is slowing the rpm down.. now if the ? is if it slows down the car at high rpm, no. it shuts the ac off at i think it is 7500 rpm..

also if your car is an 04 look in the diy forum.. there is a button push procedure to slow down the cycling of the ac..

search ac amplifier. if you cant find it send me a pm.

Here is a possibility.. if your air filter box has been opened recently, inspect it thoroughly if the box is securely fastened (the tiniest gap is enough to cause this) especially near the 2 fasteners. I heard this clicking sound on idle, with the idle being rougher than normal and sure enough it was this.

 

mmm much appreciated, I'll check for those things

 

after some experimentation it is in fact the A/C system.

A/C year round in south florida :D
