i have a 1992 toyota camry with 132,000 miles on it. when the a/c or heat is on any setting - then the idle jumps up and down from 800 rpms to 200 rmps. and the same time i hear a clicking under the hoodand the radiators fans turning on and off. any suggestions on this great site ? thankyou ~ larry

 

im pretty sure it is normal. my camry does that same thing exept for the clicking. Mine also whistles when it is ideling. idk if its the belt or wat. but still ya i think it is just normal
