Corolla big body GLI high idle

i dipped the sensor in tap water right now and the resistance is currently at 1.63 kohms...

would a bad head gasket cause high idle? suspected kasi na masama ang head gasket ng corollang ito...

start with the obvious and simple ones first. don't wish for a major damage. if the cylinder head gasket was leaking, it could
a. create a misfire
b. leak fluids
c. leak gases.
d. engine run too hot
e. lose coolant
f. engine oil emulsification (milkshake)

so far you have no mention of any of the above. don't wish for an unnecessary expense and inconvenience

well, coolant kasi is bubbling if you start it in the morning. (will post pic tom) and theres this sound when the engine is hot (parang boiling water)

anyway, forgot to mention how i checked the iacv. from here: http://alflash.com.ua/idlet.htm i checked the resistance when hot terminal RSC is at 17 ohms RSO is at 23 ohms. I also checked if the valve works by connecting B to the battery and RSO/RSC and tumataas and bumababa naman ang idle... perhaps a computer scanning would identify the problem?
