Most cans of spray I see say it is safe for AIC sensors So I usually clean while running is there something these companies arent telling us, SLOWASS?

 

nah its not that. i just have heard of quite a few people having IAC problems when the cleaned the iac and didnt let them dry fully before installing. so, just as a safe precaution, i tell everyone to make sure its all fully dry before putting the sensors back in and reinstalling the throttle body.
