Hello nicoclub, I have found out that my rb25det equipped s14 does not have a maf sensor. Guy that I bought it off of said the maf was going bad so everytime you go to turn the car on you have to disconnect the connector that connects to the TPS sensor and another wire. I searched and searched everywhere where a maf would be, but nope no where. But then I came to the conclusion that it might have another sensor that reads air temp or measures it, as it has a Haltech pro plug in Ecu. Which can use other sensors rather then sticking to the maf. So where should I check, do to figure out this problem? Any help would be much appreciated guys. Need to figure this out so I can skip to other things.
