  1. Problems, Maintenance, and Repair (Gen 4)
    It may or may not be a waste of time and money, but I decided to paint the exhaust system of my 2021 XSE with Rustoleum high heat primer and paint. Part of the process is to cure the paint by doing the following: Idle for 10 minutes - cool down. Idle for 20 minutes - cool down. Drive normally...

    Hey Guys, The first time I noticed this was a week ago when the outdoor temp was in the high 80's. Turned AC on Max, front only and waited parked with engine running for a few mins before setting out. Only lukewarm air came out of the upper vents, the mode the vents were set for. I...

    Our 05 Sienna has been a beast for 300,000 miles without fail now but yesterday it started overheating when the motor is idling and the a/c starts blowing out hot air. When I drive it cools to the proper point but then heats up again when stopped. The fans are working properly and kicking on...

    I was getting a rough idle when at a stop (accelerates fine) and got code P0354 so I changed out the #4 (front center) ignition coil. That fixed that problem. Since I have 120000 miles on my 2007 Sienna I also changed all 6 plugs. With everything apart, I cleaned the throttle body. In the...

    Hi all, I have Toyota Sienna 2001 LE. It ran great for 6 years without any trouble. Around last month, it was not going over 30 Miles and even rpm was not going over 2000 regardless how much gas I apply. One of the mechanic ran the OBD II scanner and got Knock Sensor codes.Mechanic replaced...

    Hi all. I picked up a 2007 CE from a local Toyota dealer with 27000 kms on it. Yes, very low km's and the thing is mint. Anyways, I have noticed an intermittent problem that happens when I'm in drive. When i come to a stop and want to start again (like a stop sign or traffic light) the van...
  8. Problems, Maintenance, and Repair (Gen 2)
    So, we bought a 2004 Toyota Sienna about a month ago (as-is of course.) Little did we know all the problems with it (power sliding door, catalytic converter, exhaust, abs sensor, O2 sensors, and now the ac!) Anyhow, my main problem/concern is the AC with summer approaching. It's been in and out...

    Hi, I am new to this website and have a question regarding my 2002 Sienna XLE. I purchased the van in June of 2014 and as the months went by it has been great. Now as the cold weather is upon us (Eastern Ontario) the van Idles at 1800 rpms in the cold mornings and I can let it idle for 2-3...
  11. Problems, Maintenance, and Repair (Gen 1)
    I first noticed it when I gave someone a jump last week. At startup it revs to about 2300rpm. after ten seconds it will drop to about 1500, ten more seconds and it is back up. So if I am driving under 40mph I can feel it going up and then dropping. It will keep me moving at 38mph on the high...

    After having the timing belt replaced and the fuel injectors serviced and cleaned I got my 2005 Sienna XLE back and the idle speed was over 1,000 rpm's so I brought it back to the Independent shop and the manager said that after cleaning the injectors the computer has to be reset by...

    My 2000 Toyota Sienna steers hard at an idle in both directions. I flushed and filled the system several times and cleaned the reservior. I replaced the power steering pump with a rebuilt unit and still have the same problem. The idle does increase when I turn the wheel however it only rises to...
  14. Problems, Maintenance, and Repair (Gen 2)
    So , I have an 06 Sienna Limited. The AC blows cold at speed. If the RPM's are over 2000-2500 and higher the cold air flows. if I am at idle (stopped at a light, parked with engine running 1500 RPM or less) the AC blows less than cold (humid/non AC) air. Took it to a trusted mechanic he has...

    I had our 2007 Sienna XLE AWD (about 90,000 kms) in cottage country for a week, parked outside, in -20 to -25C (-5 to -15F) weather. It worked fine except it developed a strange noise. It is best described as a noise that a heavy tractor trailer makes when it downshifts and uses the engine...

    I've got no power steering at idle or at low speeds when the accelerator pedal is not depressed. Van is a 98 with 257,xxx km (160K miles). The power steering fluid is changed periodically with Valvoline max life ATF. I've changed the power steering pump back in the spring. I took the...

    My 2003 Toyota Sienna has been running a low idle then stalling upon starting up. It has been getting progressively worse to the point where it does it everytime. Once we get the van going on the road and running for a bit it runs fine but I'm worried that my wife would be stranded somewhere...

    Over the last month, my van has developed a very loud idle. I mean VERY LOUD. The best way to describe it is two subwoofers inside the cabin playing a very low bass note, it is horrible. It hurts my ears. The interior panels rattle from the sound frequency. However, the engine is dead...
  20. Problems, Maintenance, and Repair (Gen 2)
    2004 Sienna. One mechanic and one dealer have looked for problem, say all is well. When the car is in park, no problem. When the AC is on, and I shift to drive, the idle starts surging and I hear a clicking noise from the engine (a belt?). You have to push on brake to keep car from moving...
