if you relocate the ait sensor has this or can this cause any problems that you guys noticed.
it it worth it?
thanks

i think its called the IAT sensor, but i could be wrong. your dak will run richer which means that there will be more carbon build-up in exhaust and the some fuel will be dumped into the engine without being burned. this will result in lower gas milage. oh and carbon build-up means you will go through catylic converters every year or two. other than that, it is a good mod. you will really feel the difference in hotter and more humid weather though

Where are you relocating the sensor? Also what happens if you remove the catylic converter? I was reading through the tech manual and it basically says that the sensor is just a variable voltage resistor based on exhaust temp. So you could get rid of the sensor and run a jumper to a predermined voltage setting. This could possibly affect cold runing conditions, but you could get around your engine running to lean.

I believe the sensor is being moved behind the filter in the intake pipe
i dont know what will happen if you take out the converter

if you remove the cat, you wont pass emissions. im not sure if the sensor that you read up on is the iat sensor, but i could be wrong. all i know about the iat sensor is that it reads the air temp going into the manifold and tells the dak's computer how much fuel to mix with the air. the colder the air, the more fuel is mixed.

justa4X2 -- Actually you can pass emissions without a cat. I had mine gutted (i.e. no interals, just the shell) and it passed california emmisions. I will find the test slip and post it as proof.

Will there be any difference if you remove the cat? Will it run different or rough?

alright... i left this website for several reasons, primarily because of the copious amounts of BAD information that is transmitted through here.
If you relocate the IAT, there will not be a HUGE difference in your mileage (if any). what happens is that the computer reads the ACTUAL temperature of the air entering into the engine, instead of the residual temperature that builds up in your intake manifold. you have a cast iron manifold, so it allows for the heat to transfer easily the manifold and the sensor. the air entering your manifold is not 200 deg., but the temperature of what is coming into the intake (which is why a cold-air intake makes this a very good modification).
by moving the IAT,
"some fuel will be dumped into the engine without being burned. this will result in lower gas milage. oh and carbon build-up means you will go through catylic converters every year or two."
that will not happen. first off, you don't dump "burned" fuel into your engine. what will happen is that slightly more fuel will be inserted into the mixture, which, if coupled with a cold-air intake will produce more power by having a better mixture. you may produce slightly more carbon, but not because of anything wrong. if you were to build an IAT adjuster, that would be the case if you lower the meter all the way, but you can't do that by relocating the sensor. also, you won't be going through CAT's on a yearly basis by making this mod. the CAT's on these trucks are not all that great (in terms of longevity), but they will not burn out because of this mod.
finally, let me talk you out of removing your CAT. the CAT is there for a reason. that is to protect our environment. by removing your CAT, you are doing three things: hurting the environment, as well as possibly incurring a nice fine if you are caught (the federal penalty is $2500/cat). a friend of mine decided to remove the CAT on his Mustang GT (with 4 CATs)... total fine... $10,000 (i saw the ticket). also, by just removing your CAT, you will need to get a simulator. Also, you are not improving the performance of your V6 very much. these engines pump out some (but not a lot) of power. unless you are set up with a high-horsepower V6, you won't even need to upgrade to a high-flow CAT because of how efficiently our CAT's flow.
so, in the end... relocate your IAT will not cause CAT's to burn out, or any other problems... it is actually a very good mod to do.
and if you want really good information, check out these sites:

i hope this helps.

well i have to say that i made a pretty good guess of what the iat sensor does and i never said that the fuel was "burned." i said that some fuel will be dumped into the engine without being burned.
thanks for the info about the cat and emissions but you dont have to prove it to me
