IAT sensor location

[Krono353]

My car is the 94 gt 2.3 quad 4 dohc h.o. I'm looking for the IAT sensor which I'm told should be on or after the air filter but it isn't. I've looked on top and underneath it. My last guess is it's the sensor on the intake manifold. What I'm doing is putting a resistor in (by the way will that actually work and add a little HP like i'm told?) but I can't find the IAT. Will someone please help me?

those IA resisters are crap man! They just trick the car into thinking thiers colder air entering than it really is and ups the fuel ratio so you run rich and waste gas. I have had one on my 99 ga w/v6, it just made it get crapy gas mileage. Like around 18mpg,when it should get at least 20mpg or more.

I'm not sure where its at on the 94 2.3's, But heres this does http://www.autozone.com/images/cds/g...3d800e5756.gif

Alrighty thank you for your help, gas mileage is more important anyways.

This is from a post I actually just posted last night....

"As far as why to abort the resistor, I'll try to explain:

Your intake air temperature sensor measures the temperature of the incoming air into your engine. It measures it in "pulses" several times a second. Thus, the PCM is able to adjust the air to fuel ratio accordingly, due to colder air being denser / having more oxygen, the engine needs to use more fuel to keep the ratio correct. The reason you have more power in the winter, for example, is because your engine is recieving cooler air (and more fuel) and thus is packing more air / more power into each piston stroke, do to the air's higher density. Well if you unplug your IAT sensor, your PCM will set the default intake air temp to 32 deg F. Installing the resistor only prevents a CEL light from being displayed. When your PCM thinks the air is 32 deg, it will increase the fuel accordingly. This is suppose to "increase power", but in fact 99% of the time, you'll just be running rich, and can actually lose power. Our engines run slightly rich naturally, so this is even a worse idea for our 3.4's. And with the resistor, say you drive in the winter, and it's 10 deg one morning, you would actually be running lean, which can be very bad for your engine. So all around, there are a very few temperatures / conditions where the IAT resistor might rich-out a lean spot in the spark map and gain 1 or 2 hp, but for the most part, it can rob power, and even potentially cause problems in extreme cold. Some engines have had more success with this mod (such as leaner-running engines), but our engines sure as hell aren't one of them. I tried out the mod, and ended up removing it for the above reasons. I think I kind of covered everything. Let me know if you have any other questions."
