" have a 96 Avalon with 173,000 miles on it. It has been virtually trouble free. I am the original owner, and I have kept the vehicle maintained. However, I have noticed in the last few days that the accelerator appears to be hesistating at take off. It feels as if it does not want to go down, as if it is sticking somewhat. Has anyone experienced a similar problem or have any ideas what the problem may be? "
Missy1, I have the same car with 162K miles on it but I haven't had that problem. You might try a shot of wd-40 at the throttle body where the cable attaches to the half-moon looking wheel. I did this to the cruise control cable and it helped.

I had a similar problem w/ my 99 Avalon. It was a lease vehicle and was fixed once at purchase (50 K ago) by the dealership. It has just reoccurred a few months back. I have not looked under the hood of a 96, but I would bet it is very similar to my 99. Progressing from the airfilter to the intake manifold: 1. airfilter 2. rubber boot 3. massflow sensor 4. rubber boot 5. throttle plate or butterfly valve. This is where my problem occurred. This is what the throttle cable works and gets gummed up from time to time. A $3 can of carb cleaner, a phillips screw driver and 10 minutes remedied my problem. You loosen the rubber boot just in front of the throttle plate. Be careful as you pull it back and usually you will have room to push it down below the throttle body to expose the throttle plate which will be tannish-brown. You may have to remove several other lines and perhaps an electrical connector. Use the carb cleaner and a rag spraying and working the throttle plate back and forth cleaning this area. Pay close attention to clean where the throttle plate meets the body - the valve is in a closed position. This is where the hesitation that you speak of is occurring. Let it stand for a few minutes allowing the carb cleaner to evaporate. Re-install the boot and any lines or electrical connectors that you unplugged to gain access. Start the car, you will have to run it at high idle - give it a little gas for the first minute or so, but the idle will clean-up quickly. If you are not comfortable with doing this, tell your technician at the next service interval that you would like to have the throttle body cleaned.
I hoped this helped - it may not be the solution, but it would be the first/least expensive area I would look at.

I had the same problem on my 98 Avalon. Before you purchase any carb cleaner, make sure the bottle specifically says, "Throttle Body Cleaner". I cleaned with Valvoline Synpower Carb Choke & Throttle Body Cleaner. I did this once and about 2k miles later it started to act up again. So I decided to remove the throttle body from the engine and clean it really good. When I remove the throttle body from the engine, I noticed that there are two butterflies, one by the rubber boot as mentioned above and the second is on the opposite side of the throttle body. You can access this by removing a plate. I cleaned and cleaned, make sure you purchase as small brush (toothbrush will work) to clean out thoroughly. I reinstalled and the car drove like new. About 5k miles later, the car started to hesitate again while driving, especially bad at idle. I did some research and had to replace the Exhaust Gas Recirculation (EGR valve). At a cost of $380 dollars, I did it my self. Three screws and a wire harness. 8k miles and no problems. If I was in your situation, I would recommend the following, if you haven't done so. Replace spark plugs with OEM parts, DO NOT PURCHASE BOSCH PLATINUM PLUGS, plug wires, PCV, and fuel filter. This is what you call a car's spring cleaning schedule.

98 Avalon Transmission Shifting Hard

I have 72k miles on my Avalon. I had the trany fluid changed around 65k and noticed it is shifting hard from 2nd to third. When it is cold outside, the trany lags in 2nd gear until the thermostat temp is at its warmed up point. The fluid level is the correct level. Any suggestions??

Checking the transmission fluid

Does anyone know whether you need to keep the car running to check the transmission fluid on an '03 Avalon? This information is usually found on the dip stick, but mine doesn't specify whether you need to keep the car running or not.

This information is also usually found in the owner's manual. But for some reason, Toyota omits this info in the '03 Avalon manual. I looked at mine. Not there. The answer is YES, the engine needs to running. If the engine is off, the fluid level will probably indicate well above full. Make sure the fluid is warm by driving the car for a few minutes before checking, gear selector in Park.

2000 Avalon...Automatic Transmission...

I want to put in some transmission fluid, but I have no idea where to put it in. I think I found the stick thing where you check it, but I can't find where to add more fluid. The owner's manual is no help either. Help, please?

cowman1 - Here is a little basic help on AT's.......
The fluid goes in at the dip stick tube. Use a funnel. Measure in PINTS, not quarts, this is not motor oil.
Existing fluid should be reddish or near clear. Black may be worn out or contaminated and needs a change. Smell it. If a strong burnt odor is present, change it all, not just add.
Add slowly. Never overfill. Too much causes internal foaming. That's bad. Engine and transmission must be normal operating temp for accurate check.
You might also check for leaks on the ground or on the sides of the housing. Toyota's are very tight and do not generally leak. Anything.
Properly maintained, Toyota transmissions last 200k miles or more. Many posts in Edmunds.com attest to that.
Hope this helps...my '99 XL was perfect at 92k when traded for a loaded '03.

Avalon newbie

Hi,I'm new to this forum and find the posts very interesting.
I just bought a 2005 Avalon XLS a month ago.
It's a real smooth ride ,and I enjoy driving it. The only complaint I have is the acceleration from a dead stop is not the greatest . Anyone notice a lack of power in low gear ? My old Camry seems to take off faster . The 280HP is at it's best at the higher speeds. The dealer is going to check it out anyway. Maybe I just have to get used to it.
Thanks,
Jimmy

No lack of power in our 2005 XL, that baby takes off like a rocket from any speed. "It's not your father's Oldsmobile" - what a sleeper!!
