Hey Jack. Checking in 4 years after this video was posted to thank you very much. I just completed this service and it runs beautifully. 🙏

This was clear, sharp and down to the point with no extra lecture . Thank you 🙏

I did the 100k tune up plugs wires etc etc and it was still chugging at startup, running like garbage so I decided to try this next. IT WORKED! I cleaned the throttle body out, did about 80mph on I95 for about 3 miles or and now the Rav4 runs great with smooth startup. Thank you very much!!!!

Thank You! Really appreciate the video, the content you shared, and the precise manner you shared it, good visuals and information. I followed your directions step by step which resulted in clearing up problem I was having with slow idle almost to a stall when stopped at traffic lights or stop signs. I gave a thumbs up and subscribed. 2008 Rav 4, 4 cylinder with 233.000 miles on it. Muchas Gracious!

This is better than reading the repair manual.....thanks a bunch!

I just did this to my 2010 Rav4 V6 with 154K miles. It runs super good now. Thanks for your tips.

Once again MJ thank you. Our 08 Rav4 213000 miles never touched throttle body, intake, MAF, & Injectors. Only added some Sea Foam occasionally to fuel system.

Great video Informative I have a 2008 rav an I only clean the throttle body .really appreciate the vedio

I just took my 2016 Rav 4 with 35000 miles for its last free oil change at the Toyota dealer where I bought it new and tire rotation and balance on 2/8/21. It is now out of its warranty now. In about 15 minute they come to me and tell me that they have done a free inspection and have looked at and found that my throttle body is all sooted up and the injectors are clogged and need cleaning. I ask how much, it is $220 for one and $115 for the other. So I tell them thanks for letting me know and I would take care of the problem when I get it home myself. They say it will be finished just as soon as they run it through the car wash. Stopped on the way home and got a can of throttle body cleaner and injector cleaner to add to the gas. Got home, popped the hood, removed everything to get to the throttle body on the back side of the engine, could not see where any of it had been removed to inspect it where they could tell it was sooted up. The throttle body was clean as it could be. I put it all back together, put the can of cleaner in my shop unopened and the next time I fill up with gas I will add the bottle of injector cleaner to it. The car engine runs like new so I will write this off to them trying to up sell me their service. This is the reason I do not like taking my cars in because of all the Bull Sht up selling they try to do.

I'm working on my daughter's Rav4 2006 that's running very poorly. She got a new Corolla but will sell the Rav4. this video will be very helpful. I replaced plugs / coil. Improved but still not ok. Thanks for the video.

Please put out more rav4 content...

- If changing spark plugs do it after all this operation, oil also. And wash/ clean the motor area prior. While reving the engine and adding Seafoam, you can turn the key off and carefully add a little raw Seafoam to finish, and the remaining revs/ vacuum will pull it in, coating the insides. Just let it soak the valves, piston head, and chamber a few hours. Better chance the carbon may release/ come loose later. May need a little starter fluid on restart. Good Video. Thx

After cleaning the throttle body, the first start up scarred me, it cranked for so long

The first start up took a few cranks. When it finally turned on it looked like it wants to shut off. The lights were dimming.

0:28 there is a rubber hose directly underneath the connector. Do you know the name of the hose or the name of the sensor that was disconnected?

For the next generation Rav4 after this, does that lower hose @4:10 pretty much do the same thing and go back to the intake manifold? It's so tight back there to see where the hoses are going. 😂

Currently have a 2008 rav4 with 182,279 miles on the ODO. And idles super low to 500rpms and shakes hard as hell but goes away. But I’ve noticed that at times it would be related to my AC when I had it blasting and cranked up high. But when I turned it down it would stop shaking. With that said, im going to do exactly what was done In This video and see how it turns out.

@moses2986

Update: just did exactly what was done In This video and overall the shaking and low idle pretty much gone. The idle sits just at 1000rpms even when ac on, but still shakes a little when blasting. On top of this, I did this whole service just before I took it on a 6hour drive down to a border town to see my great grandparents. And drive it an additional 6 hours back. Still runs great! So yeah recommend doing this. My odometer sitting on 183,267 currently.

Thanks for making this video. I have the same color 2006 RAV4, in a 4 cylinder as well. Just performed the throttle body cleaning on it and I think I solved an engine shuddering issue I had (dropping RPM's to 500 right when I slow down to a stop). Just wondering if anyone here has this car? If so, are you experiencing some whirring/humming noises coming from the driveline? Curious to know if you have the steering clunking noise as well? I haven't been able to definitively nail the origin of these problems, wondering if maybe you have... This car has been unstoppable aside from a few non-critical issues. The only downside I can think of is that I don't have the 3.5 V6, those are peppy for being an unassuming crossover.

I just had to replace the EVAP valve in my 08 Rav4 and now I'm getting a lot pf shaking while idling. Would this, in theory, help with that issue or would you recommend what you did with the spark plug video? Thanks for any info

@MasterJacks

Not sure what the correlation is between the evap repair and the rough idle, but doing this procedure is good maintenance and may fix your problem. Worth a try in my opinion. Spark plugs would likely have given you a check engine light for a cylinder misfire. If it's got 100k miles on it and they haven't been done, it's also good maintenance that may improve drivability..

I didn't know you could use the intake manifold port to clean past the throttle body with Sea Foam!! I've been buying the Sea Foam Top Engine cleaner with the little straw attachment. Such a pain to use because of the throttle body location which forces me to turn the bottle upside down and just makes a mess. Your way is so much easier!

@MusicIsBestDrug

4 жыл бұрын

You did a better job than the video by dispensing the Sea Foam Top Engine cleaner over Throttle Body. Why? Coz this enigne is a Direct Injection engine. It means the fuel does NOT flow over the intake valve. If it had to, it would keep the valve clean since Gasoline is excellent solvent! Intake valve being dirty and gunky with oil that comes back from PCV valve is what causes major engine problems. That seafoam in the tank is NOT going to clean your intake valve. It will only clean fuel injectors at max. The actual complete maintenance needs Fuel Injector cleaner (in this video) PLUS Sea Foam Top Engine cleaner which will indeed go over the intake valve (coz you are mixing it with air, which does go over intake valve). What you did, was a good job. You cleaned the intake valves as well (which are more important than cleaning fuel injectors)

Will cleaning the throttle body help with the long cranks when engine is warm? I heard yours crank a bit before starting up after the cleaning

@RadRob84

2 жыл бұрын

The long crank was because he sprayed throttle body cleaner directly into the engine and it was partially flooded. Best practice is to remove the throttle body from the intake and clean it with a rag. Toyota released a technical service bulletin regarding spray cleaners damaging the electronic motor through the throttle shaft.

did you use the same sea foam for the engine as you did in the gas tank?

How to change throttle body? Actually I need access to intake manifold control valve actuator, so I guess to take it out , need take out throttle body

Hi Jack, very helpful videos. I have a Rav 4 2006 4 cylinders and recently replaced the alternator, and the drive belt. Note I disconnected the car battery which I believe reset the ECU. After this I noticed the engine was running rough, which got slightly smoother over the last couple of weeks but was still happening when idling. I then replaced all spark plugs which were quite worn. Now the car runs well except when idling the Revs often drop around 500 thus vibrating the car. Would a throttle body, intake, MAF and Injector service help with this? If not what else would you suggest to do? There is no engine warning light or codes displayed on my OBDII

@MasterJacks

A dirty throttle plate can cause the symptoms you're are describing. If it were mine, I'd definitely try that first. It's cheap and good maintenance even if doesn't fix the problem. A MAF sensor can also cause erratic idle issues and not necessarily throw a code. I'd try those two things first.

Hi there, great video, car is running much better now. Just one issue I’m having, when I was doing the last part, I did just as you said, had my wife hold the gas at 2500rpm and funneled in just a little bit of sea foam, my check engine, VSC and 4wd light came on and won’t turn off now. Should I be concerned and have it diagnosed? Or should I just try to reset it? Thanks for the help!

@MasterJacks

Running the seafoam treatment can cause the engine to run rough during the procedure. If the computer isn't able to successfully compensate for the erratic idle, it will deactivate some stability control systems so as not to create a safety hazard in a system it can't fully control. This also sets a few malfunction indicator lights. If it were mine, I'd clear the code(s) with a scan tool or by disconnecting the battery. From what you've said, that should clear everything up! Let me know how it goes.

Randy Murray this car didn't have any idle problems, but I have worked on cars throwing codes for high or irratic idle caused by restricted airflow across the throttle plate. I recently serviced a Ford Focus with a code for "RPM out of range" and cleaning the throttle plate solved the problem. Electronically controlled throttle bodies are more susceptible to this fault. I did this particular service as preventative maintenance. Plugs and wires solve a lot of rough idle problems. Hope that helps!

It's not uncommon when doing this to get a misfire code which can deactivate the stability control. If it's running smooth again, I would clear the codes with a code reader and everything should be back to normal. If you don't have one of those, you could disconnect the battery negative terminal for about 1 min, then reconnect it.

@@jaychadderwala8975 my guess is that with a clean throttle body your idle rpm is lower. As the throttle gets gummed up, the computer cracks open the plate to maintain airflow, which increases rpm. Now that it's clean, it's idling back down to where it should. At stop light or reverse, there's a little bit of torque converter load on the engine (as apposed to being in park) and it lugs rpm down lower still. I wouldn't be worried about a shutter if this describes your symptoms. If the engines shakes quite a bit, could be you have a worn motor mount(s).
