my car is throwing codes.. its the intake air temperature sensor.. i have an aftermarket intake manifold.. skunk2 IM... the check engine light comes on every now and then.. once a week maybe.. not very often.. my car is 98 integra...

I'm trying to get my car tuned.. trying not to run into problems... soooo

I'm just wondering if i should replace it or clean it.. or check the ohms? i don't know.. and where is this sensor at?? can anyone get pictures?? and where could i maybe get the replacement?

thanks
