I was messing around with my intake and when I put everything back together my check engine light came on and the car almost wont idle so I check and rechecked everything to see if I missing anything and I even disc. the battery but it still wont idle for crap. anyone got any ideas??

Yeah, probably your mass air flow isn't tight or is unpluged. if not then you might not have tightened your hoses completely.

did you plug in that MAS or MAF sensor? i forget which...

It's probably the box under your intake, small black box about 12 inches long and 5 or 6 inches wide. Make sure it is snug to the main intake tube.

Did you touch the inside of the MA sensor?
Its a very fine wire looking thing, if its busted....time to get a new one

Maybe a good time to upgrade to a Injen intake or a homemade one..... I love the way my car sounds with the injen on it.

Alot of people say they hear their intake, but the only time i hear mine is when its cold outside, otherwise i hear the exhaust more........It makes this sweet sucking sound when its cold, but when warm Quiet as a mouse.....

I have the complete Injen intake with the Rod Millen big air filter and I don't hear anything or feel any changes... Replacing your intake will not solve your stalling out problem... Messing with your MAF could cause that problem, removing the mesh screen and damaging or not reinstalling will do that, loose vacume hoses or disconnected hoses may cause that problem...A bad ground wire can do that too....Even a loose snorkel tube that connects to your throttle body will mess your idle up... Re-check your MAF and electric plugs, all your vacume hoses, unplug your battery for a few minutes and re-connect then give it a go.....

jibby... if the little mesh screen is out it will cause it to do that?

I can defently hear my injen and noticed the sound the first time I started it.

I play around a lot with the air intake on my RX and I am also at about 8,000 feet where I actually live. Even if pull the EFI fuse and/or disconnect the negative battery cable, I still get what you describe and I just have to let it sit there for a few minutes, give it a little gas and be patient and eventually it comes to life. Just a function of the ECU.

Did you make sure you put the MAF in the correct position. There is an arrow on there that shows which direction the air should travel to. If thats the case, just flip around the MAF and try that.

it can, the mesh actually directs the air over the sensor to correctly read air. without it the turbulence for the air moving could have an idle spot near or at the sensor wire location. back when i worked at lexus i had a customer that sucked a rock in through the a bfi he made and it ripped through the pannel filter (this was the first and only time i've seen it happen) and damaged the honey comb...long story short we replaced the honey comb and it did fix it. a week later the sensor died but that was from him trying to clean the sensor wire.

Well the intake does make a nice sucking sound when i turn my car on, but i was assuming you guys were talking about hearing it while the car runs all the time. Cause i only hear it untill it warms up.
