Exclamation WHERE!? Intake Air Temp Sensor

Dose any body know where this is located on a 87 N/A!

I have purchased A MOD chip that requires installation in this sensor plug.
installation will be a snap, but i cant find this in the haynes manual except for in hard to read diagrams.



Any Body have a clue as to what the plug looks like, or where its located. the directions...( if you can call them that) pretty much tell me "It is in the engine bay somewhere."

It is below the BAC valve. . . or, above the oil filter, and bolted in the 'intake manifold'. There is a plug in it with black and green wires I think!?

On the dynamic chamber, drivers side, mounted to the flat area. A white harness connector plugs onto it.

But your so-called "mod" chip is nothing more then a resistor, and will do nothing to increase performance. Send it back and get a refund.

Well i understand that it is just a resistor, but dose it not accomplish what it says it dose?

Thanks for the pic. That answers my question on where it is located.

So has anyone used one of these?

I used it...it didn't do anything except mess with the idle. It also gave me horrible gas mileage I think (or it may have been from going WOT all the time testing it out). I took it out and threw it in the garbage.

No, not at all. Depending on how they advertise it, the idea is generally to fool the ECU to think that the temperature is colder then it is, thus richening up the mixture. In some cars (very few of them), this works. On the FC, which already runs pig rich from the factory, it's just going to waste gas and cost you power.

On another level, the IAT (Intake Air Temperature) sensor is there to tell the ECU basically how dense the incoming air charge is, and allow it to make adjustments based on that value. If you disable it (by installing a resistor), you are in essence making the fuel injection system dumber. You have basically locked out all the factory tuning that the computer has for varying temperature conditions, and forced it into one narrow map. Thus it may run great at say, 70 degrees air temp, but be WAY too rich at 80 degrees, and way too lean at 50 degrees.

This is simplified, but it gets the point across.
