So i got the v6 CAI from american muscle.

I installed it and now I have a Check Engine lite reflecting off the dash to the windshield starring at me tearing my heart out... sorry if im dramatic.

Any way there are two sensors and 1 vac line if i remember correctly.

1) the one sensor is already mouned and simply bolts on if I remember correctly
2) and the other is simply pushed in.

i already had the lite cleared one time and after a few hundered miles it came back on.

both times the light has come on was during idling for an excessively long time.

i forget what the code was but the guy at advanced who cleared it mentioned an 02 sensor then a vacume leak. said he didnt know. there was only one code but i forget what it said.

What is the second sensor? I may have broken it while pushing through the rubber grommet because it was really redicuclously hard to get in.

You plug the hole in on the piece of the CAI piping right before the TB? The GT's have something that goes in there but the V6's don't so we have to plug it up with something. I used a cork.

Forget to plug in your MAF? Or did you damage it in any way? If it is something to do with O2 sensors I am taking a wild guess and assuming your running either rich or lean (lean being the one I am leaning towards.... ) meaning there is un metered air getting in after the MAF which would result in that hole I was talking about not being plugged up..... Our V6's only have one Vac line that goes to the CAI btw. Not 2. Lastly, check to make sure all the rubber rings on the CAI are secure and not leaking at all. I have seen some people install the one that goes from the TB to the CAI wrong and had a bunch of extra air going in.

Make sure everything is sealed off.

ahh yes there is a slight whistle so maybe one of the clamps isnt all the way tightened.

demon are you saying that you only had one sensor bacause i have 2

Which sensors are you talking about? There are a lot of sensors that meter air in the engine... If your referring to O2's yes there is 2 on each side of the engine, but they are by the cats not the CAI.

Also the CAI itself does whistle, its the filter sucking in air. Is that pic you referred to your actual car? If so I didn't have a plug that went into that bung right next to the TB... So I can't help you there, I don't even know what it is lol.

[rafter40]

its the intake air temp sensor that i was worried about breaking

also not retarted over here except im havin trouble with the CAI so maybe I am.

no that was not my car

u can skip to 2:50 sec if u dont believe your eyes that a sensor goes there. they must have changed it in 2001

[Rich J]

I know a sensor goes there, I just thought only GT's had it. Apparently pre '01s did too. Not doubting you saying you put a random sensor in there because it fit lol. I just said to plug that hole up because thats how it is with my car and I thought all 99-04 v6's were that way. Get the codes again, we will probably be able to tell you exactly what is/could be causing that.

[mustangmike!]

Yes some V6s came with that sensor, some didnt. Thats why they say its for 99-03 and dont include 04. But thats still wrong years lol
I dont have that sensor so I cant help you.

Do post the codes you get up here and that will help us from there.

[mp4 player]

That sensor, the intake air temp sensor, was on 1999 and 2000 3.8 mustangs. Starting in 2001 this became integrated into the MAF and was no longer a separate sensor.

Just go get the CEL code read. That'll tell us a lot more than you'll be able to.

I'd suspect that you either come up with a IAT code, a MAF counts code or running lean. In any case you'll know where your problem lies then.

[rafter40]

so are we sayin the if air is leakin in behind the MAF that im getting in more air than the engine thinks so it might be a lean mixture... im sure its not my 02 sensors(mostly sure)

also nd reason the light would only come on after idle?

initially it came on rights after installation during a really long idle before driving

2nd time drove a whole lot like over 300 miles... and it came on after i had been idling for a real long time,


... ill get the codes

[Mr. Red Pony]

99-00 have external IAT. 01-04 have integrated IAT, meaning its built into the MAF. I have the built in one. Same with mike and demon.

But not really sure what you asking here guy. Be specific.

[Everett]

Put the factory airbox back on and remove the silencer,that snorkel looking thing. Then send that thing back where you bought it then spend your money on something that will give your car more pep.... Like gears and a tuner

[rafter40]

ya im not very impressed but i wasnt really expecting anything crazy.

my next performance mod will most likely be gears

this

[rafter40]

Well i know its been a while but i got the code

P0171
System to Lean
Bank 1

what do you guys think?

And tlok + tuner. Don't skip the tlok or you'll be paying for the same install twice when you realize you should have done it in the first place. And you'll need the tuner to recalibrate your speedo/tach.

I'm guessing you're getting air in after the MAF. Did you make sure all the hose clamps are tight? Did you put the gasket between the MAF and air intake tube? Did you attach the PCV hose snugly? If you look at the back of the passenger valve cover, is the PCV hose still connected? Is your PCV hose dry-rotted badly? If you rotate the tube connecting to the throttle body it will slightly slip out of place and let air in (usually at the bottom), is your air intake tube correctly positioned so there are absolutely no air leaks?

If you got the same CAI as me (the cheap one from AM) it probably came with a new PCV hose that doesn't secure to the "nipple" that attaches to the valve cover. If that slipped off then just super glue it on (mine has held up for over a year).


That black hose coming off the CAI is the one I'm talking about. It's the new one that came with my CAI and wouldn't secure to the valve cover "nipple" without an adhesive.

[rafter40]

mcqueen everything u said i have checked. Only issue is my pcv hose is really dryrotted.
i used the one that was already in my car because the one from AM didnt wanna fit. Might be because of how cold it was...

This though--- "If you rotate the tube connecting to the throttle body it will slightly slip out of place and let air in (usually at the bottom)" i am not for sure of but i have checked and found no leaks.

Also my IAT was what i thought i may have messed up. Could it throw a code like that or what would the code be.

For that part you quoted, run your fingers along the bottom of the CAI and you should be able to feel if it slipped out of the connector. You can basically feel a small gap between the tube and the connector.

I don't think it's the IAT. I'm pretty sure that throws a different code because my buddy's 96 F150 has been throwing a code that is specific to the IAT. However, did you put the IAT in so that the plastic bits are pointing towards the sides of the CAI with the sensor positioned that the air easily flows through?

And that new PCV hose is a bit of a pain in the ass to get on the CAI. If you warm it up some then it should go on a little easier.
