Never heard of that before. Yes, if it hasn't been hit try for warranty fix.

The site seems to be down. The TSB may be here: http://my.is/forums/f126/here-list-all-bul...our-car-309244/

Most of the TSB's are posted here. http://my.is/forums/f126/here-list-all-bul...our-car-309244/ They change the brake fluid because it can pick up moisture over time. You can get the brake fluid from Toyota and most any good shop can do the change out a lot cheaper. That's what I did for all the fluids on my IS300.

I'm not sure if this is the same but there's some discussion of noises here: http://us.lexusownersclub.com/forums/index...showtopic=28405 I don't think there's been a resolution to the "popping" noise.

Just disconnect the negative battery terminal for 10 minutes and then reconnect. Then start the engine, let idle for 5 or so minutes.

There's a double outlet adapter that bends 90 degrees on radioshack.com that works.

============ To be less worried please read through this forum, you'll find ample resources(complaints). If this exact situation has come up before, please link to the posts. I don't remembe seeing this come up.

The system checks take place when the engine is started, not when it's put in gear.

I think so. There should be some clips or whatever to hold those items to the airbox or next to it. So except for the strange IAT reading you should be in good shape.

UUmmm, your lucky I like you... :) Well, I had a LT1 Firebird and the IS350 made a good substitute for that.

I'm getting dumb too. I haven't even looked under the hood of a IS300 for over two years.

I think that's right and then the whole assembly of hoses, solenoid, etc has to connect to the fitting(s) on the bottom of the air box. Reach or look under the airbox and you should find empty fitting(s).

There should be no hose where that one is now.

I agree. Unless you're a person who just loves to shift gears, get the auto. Even better for something fast, get the IS350.

We was busy being geniuses simultaneously.

Not the same engine, but shows the MAF and IAT sensors. http://www.lexusownersclub.co.uk/knowledge...p;id=50&c=9

I think you need to check resistance and continuity on the IAT and wiring. That's a really high temp reading and might be the failure default reading and is part of the reason the car won't run right.

Counting left to right. Pics 6 and 7 Nothing should be hooked up to the two nipples left and right of the cam gear cover. That hose, etc should be connected at the bottom front of the airbox. That's the hose that goes to the gas tank vent/charcoal canister for the EVAP system. Last pic, that hose is hooked up correctly.

Have you looked here? There have been some for sale off and on. http://my.is/forums/f99/

Here are the codes for future reference. http://www.troublecodes.net/Lexus/

I'll look it up. P0110 IAT Circuit Malfunction Intake air temperature. I believe the IAT sensor is on the same plug as the MAF sensor, and all in the same wire bundle that plugs into the intake.

I dug out these PDF's. Find the PCV valve. The hose from that should go to the hose fitting on the round intake tube. The other hose actually comes out of the firewall on the drivers side and crosses over to the right side of the engine. That hose has to go on the fitting that sticks out at the very bottom of the air filter box. insp.pdf draw.pdf comp.pdf

If it's worth $10 to you and to save confusion just go to this link and download the tech info on the intake system http://techinfo.lexus.com/

The hoses were on both sides of the Motor does that fit the solution above ?? They're both on the passenger side of the motor as I remember. Do you have hoses or fitting on the bottom of the airbox? Are these the two hoses to which you refer? There was a guy who put on a SRT intake and he couldn't figure out where to put one of the hoses so he plugged it. His car ran like crap till we told him where to hook up the hose. So I gotta say the car won't run right till you get them right.
