anyone that did the iat sensor have probs with throwing a p0102 maf sensor code after?

Sorry I didn't see this earlier. You may have it figured out by now...

But anyway, you just need to get a multimeter and check the resistance of the wire you splice into in the harness. This is just to make sure you have the right tan wire so you aren't scratching your head wondering what happened when its just the wrong wire. Resistance should be less than 1 ohm since it will be a straight wire.

Did you cut that black wire or just splice into it? I believe they run off the same +5v input, so if you cut that to wire in your IAT sensor, your MAF won't be getting any power. You'll need it unless you are running a speed density tune.

When i ohmed mine out it showed the solid tan wire but when i tied it in it threw a maf code and a iat code so i soldered the tan back and tied 2 the tan with black chaser and no more iat code and the sensor is reading according to my scanner but i still have a maf code!? I tried a new maf sensor and still throws the code as soon as truck starts. Anyone have any ideas!?

Thanks smokeshow that was the prob! Now the only other prob i have is when i start the truck up it pulls 60+psi but after it runs for a little but or i hit the gas the pressure drops down to around 44psi!? I had tried hooking up a keene bell boost a pump that kb had given me with the kit but it was only putting out 6.75volts 2 the pump so i soldered the factory pump feed wire back together and this is happening, doh! Whats the best way 2 check voltage 2 the fuel pump without probing a wire?
