Like a lot of other people, I've had a problem with my 2006 Toyota RAV4 which can best be described as a throttle lag, hesitation, low power, acceleration, or stalling problem. In short, you press on the gas, and nothing happens, and in fact, the car seems to lose power or "bog down."
A second problem that may be related is that when I turn left or right through a large intersection, the RAV4 has the same lag/hesitation/stall/low-power problem.
While the local mechanic hasn't been able to fix the problem, lately I've taken to shifting the car down into third and second gears when I know this problem is about to happen, or just after it happens. Shifting down to a lower gear forces the RPMs to increase, and the lag/hesitation problem either isn't a problem at higher RPMs, or it is much less of a problem.
A possible RAV4 lag/hesitation/stalls/acceleration solution
This morning I tried one possible solution to this 2006 RAV4 lag/hesitation/stalling problem. This solution involves cleaning a small gadget under your hood called a "Mass Air Flow sensor", or MAF sensor.
While this may sound intimidating, it is probably the easiest car repair I have ever attempted, and isn't much more difficult than changing your air filter or your wiper blades. (Truthfully, some wiper blades have been harder to install than this work.)
I don't have much to add to that person's article, other than to say there is a better cleaning product you should use these days. I talked to the man at the NAPA store, and he handed me a product named "Mass Air Flow Sensor Cleaner", and it's made by the same company, CRC. Also, I recommend reading the back of the MAF sensor cleaner can, as it specifically states that you shouldn't use this fluid on certain vehicles, including "most Lexus vehicles."
Did this fix my RAV4 acceleration problem? Well, I don't know for sure yet, but I did take my RAV4 out for a test drive immediately, and yes, it seems much better. Actually, it felt great, but the weather is also a little warmer here today, in the upper 50s, so I'm a little hesitant to say this is a complete solution for my RAV4 hesitation/acceleration problem. The "stalling" problem seems worse when the weather is cooler or wetter, and that's one reason my local mechanic hasn't been able to make much progress. That being said, I'm very disappointed that the mechanic never said anything about cleaning the RAV4 MAF sensor for this lag/power/hesitation/stalling problem. (Sorry, I don't know what to call it, so I keep repeating those keywords, hoping they will help other RAV4 owners find this article.)
I'll report more here as I learn it, but for today, cleaning the MAF sensor certainly seems to help the 2006 RAV4 low power, hesitation, lagging problem. (Note that this same problem is probably present in 2007, 2008, and possibly 2009 RAV4 vehicles, as I think they all use the same engine.)
There’s just one person behind this website; if this article was helpful (or interesting), I’d appreciate it if you’d share it. Thanks, Al.
Anyone ever consider a class action lawsuit against Toyota for poor gas mileage ratings? My 4 cylinder engine was rated at 30mpg and I'm happy to get 24 with all highway driving. What a joke...
Also, so many people complain about the way the transmission bogs or quits, or suddenly downshifts and screams in the next gear. I think it is horrible software or powermanagement that the transmission doesn't know what to do in these situations. You'd think they would've found this situation in their pilot builds and road tests.
Recently my check engine light came on along with the VSC and traction control light and the engine started to hesitate. I'm thinking its an oxygen sensor but I'll check the MAF sensor like the previous post mentioned...
I will buy american next time.
Just called the 1-800-331-4331 number to get Toyota to pay for my intermediate shaft which causes the klunk. He said he is sorry i read about so many issues with other 2006 Rav 4's but can only go by the actual customer calling them, and can't trust online blogs as being true. EVERYONE needs to call and make your complaint known. They need to recall this. He said potentially they would pay you back if they do recall it, but was so appologetic and sympathized with my concerns. I own all Toyota's and have NEVER had an issue that was not handled asap. I told him i was done with Toyota and he said he is sorry to hear that. WOW......so please everyone call in and make them have to work to be sorry.
This info was very helpful and solved my rough ride issue..... the ride is smoother than ever.
Thanks a million.
