#2432 of 3629 1998 TOYOTA AVALON IDLE AIR CONTROL VALVE
Oct 19, 2003 (5:13 pm)
My car in the mornings always starts to shake and the RPM's would bounce around like 100 up or down. I think this is because of the Idle Air Control Valve. I am wondering how do I clean it. I heard it is very easy but where is it and how do I take it apart and clean it. Please help me as i dont want to pay dealer's rediculous prices

#13, your IAC is on the underside of the throttlebody. To keep mechanics employed, Toyo makes it hard to get to. You have to remove the throttlebody, then the IAC can be removed. It should be held by four screws. There will be an electrical connection, and some smaller air hoses connected to it... I guess you can try to clean it??? I never have. It is a "valve" system which allows more air into the throttlebody when cold. You'll see the in and out chambers on it and perhaps you'll see the valve and what needs to be cleaned???? Never thought about cleaning/rebuilding it-Sorry! Hope this gets ya' closer. -nomad56-
#2434 of 3629 "Check-Engine Light" problems
Oct 25, 2003 (7:31 pm)
I bought my 2003 Avalon in September of last year. About three months ago the yellow "Check Engine Light" (above the odometer) came on and stayed on.
Several days later I took the car in to Savannah Toyota (where I bought it) and after running a diagnostic test the technician, according to the invoice, "Replaced Charcoal Canister." (On the invoice I also see "PULLED PO441, 442, 446", whatever that means.) The light did go out, but two days later (July 30th) the "Check Engine Light" came on again and stayed on.
A few days ago I finally got around to taking the car in again and had a second diagnostic test done. This time the invoice reads "PO 440, 441 VAC. VALVE SWITCH INOP REPLACED." So I assume that means some sort of valve switch was replaced. In any case, today the "Check Engine Light" came on once more and has stayed on.
Has anyone had a similar problem, and, if so, how was it resolved? Both times I've wasted approximately three hours at Savannah Toyota, and this is really starting to get annoying.
#2435 of 3629 Avalon versus 2004 Prius
Oct 28, 2003 (6:34 pm)
I really love my Avalon but due to declining years and not doing extensive highway traveling, my wife and I no longer need this large a car. Its the best car I have ever owned or driven. No problems.
Since I am an environmentalist, I am trading for the 2004 Prius with all options. I have driven it and its pretty good. Rides nice and smoooooth. Ordered mine about 2 months ago when first announced and it is to be delivered to dealer next Monday. As soon as I figure how to use all the touch screens, am sure I will enjoy it. The Navigation Screen contains the BlueTooth system for cell phone use automatically as long as you have the cell phone on your person.

I can well understand you liking the Prius. The salesman who sold me my 03 XLS drove me in one of these to get my car from another dealer. I too was very impressed at the smooth quiet ride of that car. It's amazing really. Heck, if I didn't need the room I too would have considered that car. I think it is leading all others in that area. Nicely executed indeed. Good luck with that.

went to test drive this car today and I was impressed by the ride as well as the enormous room this car has. I can however do without the huge and ugly monstrosity they call the stickshift and the hideous console they have. What a disservice to a near-luxury car.

I realize that beauty IS in the eye of the beholder, but the Avalon console and shift lever are rather typical of near-luxury cars, regardless of whether the shift is on the column or on the floor. I'm not familiar with the console appearance when fitted with the optional navigational screen, but most of these do look awful regardless of the make or model.

Sure do appreciate your suggestions re: my "gurgling noise". I went to my dealer and had all the things checked that you mentioned, but all were okay. Then we discussed the gas - he told me that Sam's Club gas (which I had been using exclusively) may be inferior to some other brands. He suggested that I wait until the tank is almost empty, then fill up on a different brand. He mentioned several places to go. So I did that, using high-test 9l Octane, and added a can of BG K-44 additive. It has been 2 weeks now, and NO MORE GURGLING NOISE ! (average mileage around town is 25 MPG) I'm ready to gas up again & will use regular octane. Hopefully, my problem has been solved....and I do appreciate all the input. It's great to have brains to pick when you have a problem !!
#2440 of 3629 A Re-Design is needed
Nov 03, 2003 (12:20 pm)
I have a 2001 XLS and love it. This is really the best car that I have ever owned. I used it for 2.5 years for business (Hwy.) driving and it was fantastic. I just purchased a 03 TL Type S because it is "Younger in Appearance" and has alot more power. I hope that Toyota can re-design the Avalon and bring it into the class with the TL's or G-35's. The 210hp engine is fine but with a new design, more HP, and better wheels, Toyota may see an increase in their sales.
Just my two cent worth of thoughts this Monday afternoon.

Just replaced my Michelin MXV4 Plus front tires with Nokian WR all WEATHER tires. The Michelins are adequate in the snow, but, not a real snow biting tread pattern, unfortunately in the north east corner of NY I need them for more than a couple of weeks. I'll let the board know how they are when the inevitable comes.
