1986.5 Idling at high RPMS
 
I was wondering if anyone had any thoughts on why my 1986.5 Toyota Supra is currently idling at high RPM's. I've cleaned the throttle body thuroghly tighten my accelerator cords attached to the throttle body. Just wondering if anyone has had this problem and wht they've done ot fix it. My Supra is currently idling at about 1700 rpms ( before i did all the work i've done it was redlining, then it droped to 3000 rpms then to 1700 rpms) if anyone has any thoughts please share them with me. Thanks

you say you tightened the accelerator cords
turn the car off, take OFF the throttle cable from the linkage/butterfly then start it and see what happends

Many cars with clutch fans will idle at a higher RPM occasionally to cool the engine more efficiently. This is because it'll blow more air at a slightly higher speed without increasing the temperature of the engine too much. This would be a computer controlled function, and if it only happens every now and then, it's normal.
