My idle sticks at 1800 rmp when it's hot and humid out. It did it last summer but not all winter and its doing it again. It doesnt do it every time and it isn't always stuck at 1800. Sometimes 1500 and just goes down really slow when i put the clutch in. My check engine light doesnt work so I don't know if that would be on or not. Does anyone have any idea what this could be?

Check Idle Air Control valve that is attched to the side of the TB. May need to be cleaned out. Also check the voltage to the TPS.

I've cleaned my IAC and that didnt fix it. But I didn't check the voltageto the TPS.

The voltage should fall between .90-1.00 volts.
